Skin Cancer Detection using Digital Image Processing and Implementation using...ijtsrd
Melanoma is a serious type of skin cancer. It starts in skin cells called melanocytes. There are 3 main types of skin cancer, Melanoma, Basal and Squamous cell carcinoma. Melanoma is more likely to spread to other parts of the body. Early detection of malignant melanoma in dermoscopy images is very important and critical, since its detection in the early stage can be helpful to cure it. Computer Aided Diagnosis systems can be very helpful to facilitate the early detection of cancers for dermatologists. Image processing is a commonly used method for skin cancer detection from the appearance of affected area on the skin. In this work, a computerised method has been developed to make use of Neural Networks in the field of medical image processing. The ultimate aim of this paper is to implement cost-effective emergency support systems to process the medical images. It is more advantageous to patients. The dermoscopy image of suspect area of skin cancer is taken and it goes under various pre-processing technique for noise removal and image enhancement. Then the image is undergone to segmentation using Thresholding method. Some features of image have to be extracted using ABCD rules. In this work, Asymmetry index and Geometric features are extracted from the segmented image. These features are given as the input to classifier. Artificial Neural Network ANN with feed forward architecture is used for classification purpose. It classifies the given image into cancerous or non-cancerous. The proposed algorithm has been tested on the ISIC International Skin Imaging Collaboration 2017 training and test datasets. The ground truth data of each image is available as well, so performance of this work can evaluate quantitatively.

This document presents a novel method for automatically segmenting skin lesions in macroscopic images using iterative stochastic region merging based on discrete wavelet transformation. It aims to address challenges like illumination variation, presence of hair, irregular skin color variation, and multiple unhealthy skin regions. The method divides an input image into regions, extracts features like color, texture, skewness and kurtosis, then classifies the image using knowledge-based classification. Experimental results on 60 real images show the proposed method achieves lower segmentation error than level set active contours, skin lesion segmentation, and multidirectional gradient vector flow methods.

Melanoma Skin Cancer Detection using Image Processing and Machine Learningijtsrd
Dermatological Diseases are one of the biggest medical issues in 21st century due to its highly complex and expensive diagnosis with difficulties and subjectivity of human interpretation. In cases of fatal diseases like Melanoma diagnosis in early stages play a vital role in determining the probability of getting cured. We believe that the application of automated methods will help in early diagnosis especially with the set of images with variety of diagnosis. Hence, in this article we present a completely automated system of dermatological disease recognition through lesion images, a machine intervention in contrast to conventional medical personnel based detection. Our model is designed into three phases compromising of data collection and augmentation, designing model and finally prediction. We have used multiple AI algorithms like Convolutional Neural Network and Support Vector Machine and amalgamated it with image processing tools to form a better structure, leading to higher accuracy of 85 .

Segmentation and Classification of Skin Lesions Based on Texture FeaturesIJERA Editor
Skin cancer is the most common type of cancer and represents 50% all new cancers detected each year. The deadliest form of skin cancer is melanoma and its incidence has been rising at a rate of 3% per year. Due to the costs for dermatologists to monitor every patient, there is a need for an computerized system to evaluate a patient‘s risk of melanoma using images of their skin lesions captured using a standard digital camera. In Proposed method, a novel texture-based skin lesion segmentation algorithm is used and to classify the stages of skin cancer using probabilistic neural network. Probabilistic neural network will give better performance in this system to detect a lot of stages in skin lesion. To extract the characteristics from various skin lesions and its united features gives better classification with new approached probabilistic neural network. There are five different skin lesions commonly grouped as Actinic Keratosis (AK), Basal Cell Carcinoma (BCC), Melanocytic Nevus / Mole (ML), Squamous Cell Carcinoma (SCC), Seborrhoeic Keratosis (SK). The system will be used to classify the queried images automatically to decide the stages of abnormality. The lesion diagnosis system involves two stages of process such as training and classification. Feature selection is used in the classified framework that chooses the most relevant feature subsets at each node of the hierarchy. An automatic classifier will be used for classification based on learning with some training samples of each stage. The accuracy of the proposed neural scheme is higher in discriminating cancer and pre-malignant lesions from benign skin lesions, and it attains an total classification accuracy is high of skin lesions.
IRJET- Analysis of Skin Cancer using ABCD TechniqueIRJET Journal
This document describes a proposed method for analyzing skin cancer using the ABCD technique. It begins with an introduction to skin cancer and melanoma. The proposed method involves preprocessing the skin lesion image using filters to reduce noise, segmenting the lesion from the image, extracting features using the ABCD parameters of asymmetry, border, color, and diameter, and then identifying malignant melanoma based on the feature analysis. If melanoma is detected early using this technique, it could help reduce healthcare costs by lowering the need for biopsies. The method aims to accurately detect melanoma for early treatment when survival rates are highest.
RECOGNITION OF SKIN CANCER IN DERMOSCOPIC IMAGES USING KNN CLASSIFIERADEIJ Journal
The largest organ of the body is human skin. Melanoma is a fastest growing & deadliest cancer which starts in pigment cells (melanocytes) of the skin that mostly occurs on the exposed parts of the body. Early detection is vital in treating this type of skin cancer but the time and effort required is immense. Dermoscopy is a non invasive skin imaging technique of acquiring a magnified and illuminated image of a region of skin for increased clarity of the spots on the skin The use of machine learning and automation of the process involved in detection will not only save time but will also provide a more accurate diagnosis. The skin images collected from the databases cannot be directly classified by the automation techniques. The reason is twofold: (a) Lack of clarity in the features which is mainly due to the poor contrast of the raw image and (b) Large dimensions of the input image which causes the complexity of the system. Hence, suitable techniques must be adopted prior to the image classification process to overcome these drawbacks. The first drawback can be minimized by adopting suitable pre- processing techniques which can enhance the contrast of the input images. The second drawback is solved by incorporating the feature extraction technique which reduces the dimensions of the input image to high extent. Further, K-NN (K-Nearest Neighbor) classifier is used for classification of the given image into cancerous or non- cancerous.
11.[37 46]segmentation and feature extraction of tumors from digital mammogramsAlexander Decker
This document summarizes a proposed computer-aided detection (CAD) system for segmenting tumors and extracting features from digital mammograms to help radiologists diagnose breast cancer. The proposed CAD system includes five stages: 1) collecting input images and extracting regions of interest, 2) enhancing the regions of interest, 3) segmenting the tumors, 4) filtering noises, and 5) extracting texture and statistical features. Texture features like Haralick features extracted from gray-level co-occurrence matrices are calculated to classify tumors as benign or malignant. The system is tested on mammogram images from the Mammographic Image Analysis Society database to evaluate the segmentation and feature extraction methods.
Skin Cancer Recognition Using SVM Image Processing TechniqueIJBNT Journal
Skin cancer is considered as commonest cause of death among humans in today’s world. This type of cancer shows non uniform or patchy growth of skin cells that most commonly occurs on of the certain parts of body which are more likely exposed to the light, but it can occur anywhere on the body. The majority of skin cancers can be treated if detected early. As a result, finding skin cancer early and easily will save a patient’s life. Early detection of skin cancer at an early stage is now possible thanks to modern technologies. Biopsy procedure [1] is a systematic method for diagnosis skin cancer. It is achieved by extracting skin cells, after which the sample is sent to different laboratories for examination. It’s a very long (in terms of time) and painful process. For primitive detection of skin cancer disease, we proposed a skin cancer detection system based on svm. It is more helpful to patients. Various methods of image processing and the supervised learning algorithm called Support Vector Machine (SVM) are used in the identification process. Epiluminescence microscopy is taken using an image and particular to several pre processing techniques which are used in the reduction of sound artifacts and improvise quality of images. Segmentation is done by using certain thresholding techniques like OTSU. The GLCM technique must be used to remove certain image features. These characteristics are fed into the classifier as input. The Supervised learning model called (SVM) is used to distinguish data sets. It determines whether a picture is cancerous or not.
Skin Cancer Prognosis Based Pigment ProcessingCSCJournals
This document presents a new computer vision method for skin cancer prognosis based on pigment processing and symmetry analysis. It describes two pigment matching procedures - Procedure #1 matches pigments to artificial color spectrums, while Procedure #2 matches pigments to a malignant pigment database. Procedure #1 achieved 80% accurate classification, while Procedure #2 achieved 92.5% accuracy when tested on 40 pre-classified images. The higher accuracy of Procedure #2 suggests that using true color values from lesions is better than artificial spectrums for pigment matching.

SkinCure: An Innovative Smart Phone Based Application to Assist in Melanoma E...sipij
Melanoma spreads through metastasis, and therefore it has been proven to be very fatal. Statistical
evidence has revealed that the majority of deaths resulting from skin cancer are as a result of melanoma.
Further investigations have shown that the survival rates in patients depend on the stage of the infection;
early detection and intervention of melanoma implicates higher chances of cure. Clinical diagnosis and
prognosis of melanoma is challenging since the processes are prone to misdiagnosis and inaccuracies due
to doctors’ subjectivity. This paper proposes an innovative and fully functional smart-phone based
application to assist in melanoma early detection and prevention. The application has two major
components; the first component is a real-time alert to help users prevent skin burn caused by sunlight; a
novel equation to compute the time for skin to burn is thereby introduced. The second component is an
automated image analysis module which contains image acquisition, hair detection and exclusion, lesion
segmentation, feature extraction, and classification. The proposed system exploits PH2 Dermoscopy image
database from Pedro Hispano Hospital for development and testing purposes. The image database
contains a total of 200 dermoscopy images of lesions, including normal, atypical, and melanoma cases.
The experimental results show that the proposed system is efficient, achieving classification of the normal,
atypical and melanoma images with accuracy of 96.3%, 95.7% and 97.5%, respectively.

Physical Properties, Novel Features and Clinical Validation of a Multispectral Digital Skin Lesion Analysis Device for Melanoma Detection
MelaFind is a multispectral digital skin lesion analysis device for melanoma detection and works as a non-invasive, objection computer vision system helping dermatologists in the detection of melanoma. By combining multispectral data acquisition with automatic quantitative analysis, this lesion classifier uses 75 features to evaluate the degree of 3-D morphological disorganization of pigmented lesions.
The MelaFind lesion classifier produces scores that range from -5.25 to +9.00, with scores below zero considered to be “low disorganization” and scores above to be considered “high disorganization.” A large prospective clinical study of melanoma detection showed sensitivity to melanoma and high-grade dysplastic lesions to be 98.3% with statistically higher biopsy specificity than dermatologists. In this poster, which evaluated over 1600 lesions, the average classifier score of melanomas, high-grade lesions, and non-melanoma/high grade lesions were 3.5, 2.7, and 1.6, respectively. This study validates MelaFind as a validated tool capable of aiding the dermatologist by capturing information that is not visible to the human eye to aid in the detection of high-grade dysplastic lesions as well as melanoma.
Human health is the real wealth for a society. Consequently prevention of health from complex diseases like cancer needs the diagnosis of these entire viruses at an early stage. Colon cancer, the most common one, reached the highest rate among all the other types recently. Colorectal cancer gets developed either in colon or in the rectum inside the large intestine, due to the abnormal growth of the cells. Computer-aided decision support system has become one of the major research topics in medical imaging field during the past two decades to detect cancers. Detecting and screening of colorectal cancers are done by a Computed Tomography. The implemented algorithm determines the locations and features of glands which are affected by cancer tissues and save this
information for the subsequent diagnosis. The proposed algorithm carries out the diagnosis with two modules:
One known as the gland detection and the other one referred as the nuclei detection. Gland detection is performed in the proposed algorithm using color segmentation either through HSV or LAB transformation. Noise removal and erosion of the input image is performed for enhancing the selection of the affected tissues. The boundary detection and connection is established through Markov Chain model to identify the affected tissues with proper threshold. The first module detects the glands where the possibly of miss detection is more. Hence to remove the miss detected glands the algorithm proceed for the second module referred as nuclei detection. The most well
known region growing methodology is slightly modified to increase the speed and reduce the memory size To provide the execution in low-end clients, the whole image is cracked into smaller tiles and after the processing of each individual tiles , the results are to be merged to get back the original size. After nuclei detection if the number of nucleus is more that glands are miss detected glands and they are removed.
Detection of Malignancy in Digital Mammograms from Segmented Breast Region Us...IOSR Journals
This document presents a technique for detecting malignancy in digital mammograms using morphological operations. The proposed method involves noise removal using Gaussian filtering, image enhancement, removing background information through thresholding and morphological operations, performing image subtraction on the segmented image and converted RGB image to obtain tumors, and applying erosion to reduce small scale details and region sizes. The method was tested on images from a cancer hospital and implemented in Matlab. Experimental results show the technique can effectively preprocess images and segment regions to identify malignant data for assessment. Future work may focus on improving edge detection, segmentation algorithms, and producing more accurate cancer detection results.
Image processing techniques play a significant role in many areas in life, especially
in medical images, where they play a prominent role in diagnosing many diseases such
as detection of the brain tumor, breast cancer, kidney cancer, and the fractions.
Breast cancer is a common disease, regardless of the type of this disease, whether
it is benign or malignant, it is very dangerous and early detection may reduce the risk
of the disease spreading in the body leading to death. This work presents an approach
to detect breast cancer based on image processing algorithms, including image
preprocessing, enhancement, segmentation, Morphological operations, and feature
extraction to detect and extract the breast cancer region
Computer Vision for Skin Cancer Diagnosis and Recognition using RBF and SOMCSCJournals
Human skin is the largest organ in our body which provides protection against heat, light, infections and injury. It also stores water, fat, and vitamin. Cancer is the leading cause of death in economically developed countries and the second leading cause of death in developing countries. Skin cancer is the most commonly diagnosed type of cancer among men and women. Exposure to UV rays, modernize diets, smoking, alcohol and nicotine are the main cause. Cancer is increasingly recognized as a critical public health problem in Ethiopia. There are three type of skin cancer and they are recognized based on their own properties. In view of this, a digital image processing technique is proposed to recognize and predict the different types of skin cancers using digital image processing techniques. Sample skin cancer image were taken from American cancer society research center and DERMOFIT which are popular and widely focuses on skin cancer research. The classification system was supervised corresponding to the predefined classes of the type of skin cancer. Combining Self organizing map (SOM) and radial basis function (RBF) for recognition and diagnosis of skin cancer is by far better than KNN, Naïve Bayes and ANN classifier. It was also showed that the discrimination power of morphology and color features was better than texture features but when morphology, texture and color features were used together the classification accuracy was increased. The best classification accuracy (88%, 96.15% and 95.45% for Basal cell carcinoma, Melanoma and Squamous cell carcinoma respectively) were obtained using combining SOM and RBF. The overall classification accuracy was 93.15%.

Segmentation and Classification of Skin Lesions Based on Texture FeaturesIJERA Editor
Skin cancer is the most common type of cancer and represents 50% all new cancers detected each year. The deadliest form of skin cancer is melanoma and its incidence has been rising at a rate of 3% per year. Due to the costs for dermatologists to monitor every patient, there is a need for an computerized system to evaluate a patient‘s risk of melanoma using images of their skin lesions captured using a standard digital camera. In Proposed method, a novel texture-based skin lesion segmentation algorithm is used and to classify the stages of skin cancer using probabilistic neural network. Probabilistic neural network will give better performance in this system to detect a lot of stages in skin lesion. To extract the characteristics from various skin lesions and its united features gives better classification with new approached probabilistic neural network. There are five different skin lesions commonly grouped as Actinic Keratosis (AK), Basal Cell Carcinoma (BCC), Melanocytic Nevus / Mole (ML), Squamous Cell Carcinoma (SCC), Seborrhoeic Keratosis (SK). The system will be used to classify the queried images automatically to decide the stages of abnormality. The lesion diagnosis system involves two stages of process such as training and classification. Feature selection is used in the classified framework that chooses the most relevant feature subsets at each node of the hierarchy. An automatic classifier will be used for classification based on learning with some training samples of each stage. The accuracy of the proposed neural scheme is higher in discriminating cancer and pre-malignant lesions from benign skin lesions, and it attains an total classification accuracy is high of skin lesions.
IRJET- Analysis of Skin Cancer using ABCD TechniqueIRJET Journal
This document describes a proposed method for analyzing skin cancer using the ABCD technique. It begins with an introduction to skin cancer and melanoma. The proposed method involves preprocessing the skin lesion image using filters to reduce noise, segmenting the lesion from the image, extracting features using the ABCD parameters of asymmetry, border, color, and diameter, and then identifying malignant melanoma based on the feature analysis. If melanoma is detected early using this technique, it could help reduce healthcare costs by lowering the need for biopsies. The method aims to accurately detect melanoma for early treatment when survival rates are highest.
RECOGNITION OF SKIN CANCER IN DERMOSCOPIC IMAGES USING KNN CLASSIFIERADEIJ Journal
The largest organ of the body is human skin. Melanoma is a fastest growing & deadliest cancer which starts in pigment cells (melanocytes) of the skin that mostly occurs on the exposed parts of the body. Early detection is vital in treating this type of skin cancer but the time and effort required is immense. Dermoscopy is a non invasive skin imaging technique of acquiring a magnified and illuminated image of a region of skin for increased clarity of the spots on the skin The use of machine learning and automation of the process involved in detection will not only save time but will also provide a more accurate diagnosis. The skin images collected from the databases cannot be directly classified by the automation techniques. The reason is twofold: (a) Lack of clarity in the features which is mainly due to the poor contrast of the raw image and (b) Large dimensions of the input image which causes the complexity of the system. Hence, suitable techniques must be adopted prior to the image classification process to overcome these drawbacks. The first drawback can be minimized by adopting suitable pre- processing techniques which can enhance the contrast of the input images. The second drawback is solved by incorporating the feature extraction technique which reduces the dimensions of the input image to high extent. Further, K-NN (K-Nearest Neighbor) classifier is used for classification of the given image into cancerous or non- cancerous.
11.[37 46]segmentation and feature extraction of tumors from digital mammogramsAlexander Decker
This document summarizes a proposed computer-aided detection (CAD) system for segmenting tumors and extracting features from digital mammograms to help radiologists diagnose breast cancer. The proposed CAD system includes five stages: 1) collecting input images and extracting regions of interest, 2) enhancing the regions of interest, 3) segmenting the tumors, 4) filtering noises, and 5) extracting texture and statistical features. Texture features like Haralick features extracted from gray-level co-occurrence matrices are calculated to classify tumors as benign or malignant. The system is tested on mammogram images from the Mammographic Image Analysis Society database to evaluate the segmentation and feature extraction methods.
Skin Cancer Recognition Using SVM Image Processing TechniqueIJBNT Journal
Skin cancer is considered as commonest cause of death among humans in today’s world. This type of cancer shows non uniform or patchy growth of skin cells that most commonly occurs on of the certain parts of body which are more likely exposed to the light, but it can occur anywhere on the body. The majority of skin cancers can be treated if detected early. As a result, finding skin cancer early and easily will save a patient’s life. Early detection of skin cancer at an early stage is now possible thanks to modern technologies. Biopsy procedure [1] is a systematic method for diagnosis skin cancer. It is achieved by extracting skin cells, after which the sample is sent to different laboratories for examination. It’s a very long (in terms of time) and painful process. For primitive detection of skin cancer disease, we proposed a skin cancer detection system based on svm. It is more helpful to patients. Various methods of image processing and the supervised learning algorithm called Support Vector Machine (SVM) are used in the identification process. Epiluminescence microscopy is taken using an image and particular to several pre processing techniques which are used in the reduction of sound artifacts and improvise quality of images. Segmentation is done by using certain thresholding techniques like OTSU. The GLCM technique must be used to remove certain image features. These characteristics are fed into the classifier as input. The Supervised learning model called (SVM) is used to distinguish data sets. It determines whether a picture is cancerous or not.
Skin Cancer Prognosis Based Pigment ProcessingCSCJournals
This document presents a new computer vision method for skin cancer prognosis based on pigment processing and symmetry analysis. It describes two pigment matching procedures - Procedure #1 matches pigments to artificial color spectrums, while Procedure #2 matches pigments to a malignant pigment database. Procedure #1 achieved 80% accurate classification, while Procedure #2 achieved 92.5% accuracy when tested on 40 pre-classified images. The higher accuracy of Procedure #2 suggests that using true color values from lesions is better than artificial spectrums for pigment matching.

SkinCure: An Innovative Smart Phone Based Application to Assist in Melanoma E...sipij
Melanoma spreads through metastasis, and therefore it has been proven to be very fatal. Statistical
evidence has revealed that the majority of deaths resulting from skin cancer are as a result of melanoma.
Further investigations have shown that the survival rates in patients depend on the stage of the infection;
early detection and intervention of melanoma implicates higher chances of cure. Clinical diagnosis and
prognosis of melanoma is challenging since the processes are prone to misdiagnosis and inaccuracies due
to doctors’ subjectivity. This paper proposes an innovative and fully functional smart-phone based
application to assist in melanoma early detection and prevention. The application has two major
components; the first component is a real-time alert to help users prevent skin burn caused by sunlight; a
novel equation to compute the time for skin to burn is thereby introduced. The second component is an
automated image analysis module which contains image acquisition, hair detection and exclusion, lesion
segmentation, feature extraction, and classification. The proposed system exploits PH2 Dermoscopy image
database from Pedro Hispano Hospital for development and testing purposes. The image database
contains a total of 200 dermoscopy images of lesions, including normal, atypical, and melanoma cases.
The experimental results show that the proposed system is efficient, achieving classification of the normal,
atypical and melanoma images with accuracy of 96.3%, 95.7% and 97.5%, respectively.

Physical Properties, Novel Features and Clinical Validation of a Multispectral Digital Skin Lesion Analysis Device for Melanoma Detection
MelaFind is a multispectral digital skin lesion analysis device for melanoma detection and works as a non-invasive, objection computer vision system helping dermatologists in the detection of melanoma. By combining multispectral data acquisition with automatic quantitative analysis, this lesion classifier uses 75 features to evaluate the degree of 3-D morphological disorganization of pigmented lesions.
The MelaFind lesion classifier produces scores that range from -5.25 to +9.00, with scores below zero considered to be “low disorganization” and scores above to be considered “high disorganization.” A large prospective clinical study of melanoma detection showed sensitivity to melanoma and high-grade dysplastic lesions to be 98.3% with statistically higher biopsy specificity than dermatologists. In this poster, which evaluated over 1600 lesions, the average classifier score of melanomas, high-grade lesions, and non-melanoma/high grade lesions were 3.5, 2.7, and 1.6, respectively. This study validates MelaFind as a validated tool capable of aiding the dermatologist by capturing information that is not visible to the human eye to aid in the detection of high-grade dysplastic lesions as well as melanoma.
Human health is the real wealth for a society. Consequently prevention of health from complex diseases like cancer needs the diagnosis of these entire viruses at an early stage. Colon cancer, the most common one, reached the highest rate among all the other types recently. Colorectal cancer gets developed either in colon or in the rectum inside the large intestine, due to the abnormal growth of the cells. Computer-aided decision support system has become one of the major research topics in medical imaging field during the past two decades to detect cancers. Detecting and screening of colorectal cancers are done by a Computed Tomography. The implemented algorithm determines the locations and features of glands which are affected by cancer tissues and save this
information for the subsequent diagnosis. The proposed algorithm carries out the diagnosis with two modules:
One known as the gland detection and the other one referred as the nuclei detection. Gland detection is performed in the proposed algorithm using color segmentation either through HSV or LAB transformation. Noise removal and erosion of the input image is performed for enhancing the selection of the affected tissues. The boundary detection and connection is established through Markov Chain model to identify the affected tissues with proper threshold. The first module detects the glands where the possibly of miss detection is more. Hence to remove the miss detected glands the algorithm proceed for the second module referred as nuclei detection. The most well
known region growing methodology is slightly modified to increase the speed and reduce the memory size To provide the execution in low-end clients, the whole image is cracked into smaller tiles and after the processing of each individual tiles , the results are to be merged to get back the original size. After nuclei detection if the number of nucleus is more that glands are miss detected glands and they are removed.
Detection of Malignancy in Digital Mammograms from Segmented Breast Region Us...IOSR Journals
This document presents a technique for detecting malignancy in digital mammograms using morphological operations. The proposed method involves noise removal using Gaussian filtering, image enhancement, removing background information through thresholding and morphological operations, performing image subtraction on the segmented image and converted RGB image to obtain tumors, and applying erosion to reduce small scale details and region sizes. The method was tested on images from a cancer hospital and implemented in Matlab. Experimental results show the technique can effectively preprocess images and segment regions to identify malignant data for assessment. Future work may focus on improving edge detection, segmentation algorithms, and producing more accurate cancer detection results.
Image processing techniques play a significant role in many areas in life, especially
in medical images, where they play a prominent role in diagnosing many diseases such
as detection of the brain tumor, breast cancer, kidney cancer, and the fractions.
Breast cancer is a common disease, regardless of the type of this disease, whether
it is benign or malignant, it is very dangerous and early detection may reduce the risk
of the disease spreading in the body leading to death. This work presents an approach
to detect breast cancer based on image processing algorithms, including image
preprocessing, enhancement, segmentation, Morphological operations, and feature
extraction to detect and extract the breast cancer region
Computer Vision for Skin Cancer Diagnosis and Recognition using RBF and SOMCSCJournals
Human skin is the largest organ in our body which provides protection against heat, light, infections and injury. It also stores water, fat, and vitamin. Cancer is the leading cause of death in economically developed countries and the second leading cause of death in developing countries. Skin cancer is the most commonly diagnosed type of cancer among men and women. Exposure to UV rays, modernize diets, smoking, alcohol and nicotine are the main cause. Cancer is increasingly recognized as a critical public health problem in Ethiopia. There are three type of skin cancer and they are recognized based on their own properties. In view of this, a digital image processing technique is proposed to recognize and predict the different types of skin cancers using digital image processing techniques. Sample skin cancer image were taken from American cancer society research center and DERMOFIT which are popular and widely focuses on skin cancer research. The classification system was supervised corresponding to the predefined classes of the type of skin cancer. Combining Self organizing map (SOM) and radial basis function (RBF) for recognition and diagnosis of skin cancer is by far better than KNN, Naïve Bayes and ANN classifier. It was also showed that the discrimination power of morphology and color features was better than texture features but when morphology, texture and color features were used together the classification accuracy was increased. The best classification accuracy (88%, 96.15% and 95.45% for Basal cell carcinoma, Melanoma and Squamous cell carcinoma respectively) were obtained using combining SOM and RBF. The overall classification accuracy was 93.15%.

This document proposes a system for early detection of melanoma skin cancer using 3D analysis of dermoscopic images with encrypted diagnosis results. The system converts 2D skin lesion images into 3D images after estimating depth. It extracts 3D shape and depth features from the reconstructed 3D image. Two classifiers (AdaBoost and multi-class SVM) are used to diagnose different skin lesions and melanoma stages. RSA encryption is then applied to the diagnosis results to securely transmit them. According to performance metrics on a public skin image dataset, the multi-class SVM classifier achieved 98.69% accuracy compared to 92% for AdaBoost, demonstrating the potential of this 3D analysis and encrypted diagnosis system.
Hybrid channel and spatial attention-UNet for skin lesion segmentationIAESIJAI
Melanoma is a type of skin cancer which has affected many lives globally. The American Cancer Society research has suggested that it a serious type of skin cancer and lead to mortality but it is almost 100% curable if it is detected and treated in its early stages. Currently automated computer vision-based schemes are widely adopted but these systems suffer from poor segmentation accuracy. To overcome these issue, deep learning (DL) has become the promising solution which performs extensive training for pattern learning and provide better classification accuracy. However, skin lesion segmentation is affected due to skin hair, unclear boundaries, pigmentation, and mole. To overcome this issue, we adopt UNet based deep learning scheme and incorporated attention mechanism which considers low level statistics and high-level statistics combined with feedback and skip connection module. This helps to obtain the robust features without neglecting the channel information. Further, we use channel attention, spatial attention modulation to achieve the final segmentation. The proposed DL based scheme is instigated on publically available dataset and experimental investigation shows that the proposed Hybrid Attention UNet approach achieves average performance as 0.9715, 0.9962, 0.9710.
IRJET- Color and Texture based Feature Extraction for Classifying Skin Ca...IRJET Journal
This document presents a method to classify skin cancer images as malignant or benign using color and texture feature extraction with support vector machine (SVM) and convolutional neural network (CNN) classifiers. The method segments skin cancer images from the ISIC dataset using active contour modeling. Color features are extracted using histogram analysis in HSV color space. Texture features like mean, variance, skewness and kurtosis are calculated statistically. Both SVM and CNN are used to classify the images based on these features, and CNN achieves higher average accuracy than SVM. The CNN approach is therefore proven more effective for skin cancer classification using color and texture features.
An overview of automatic brain tumor detection frommagnetic resonance imagesMangesh Lingampalle
The document discusses several techniques for automatically detecting brain tumors from magnetic resonance (MR) images. It begins with an overview of MR imaging and challenges of manual tumor detection. Several existing techniques are then summarized, including thresholding-based methods, fuzzy classification with deformable models, using wavelets and statistics to segment tissues, feature extraction with Adaboost classification, and color-converted k-means clustering. The document proposes a technique using undecimated wavelet transform (UDWT) and Gabor filters for preprocessing, followed by morphological operations and parameter analysis to detect tumors. Automatic detection techniques could help address limitations of manual detection and improve diagnosis of brain tumors.
Brain tumor is a malformed growth of cells within brain which may be
cancerous or non-cancerous. The term ‘malformed’ indicates the existence of tumor. The
tumor may be benign or malignant and it needs medical support for further classification.
Brain tumor must be detected, diagnosed and evaluated in earliest stage. The medical
problems become grave if tumor is detected at the later stage. Out of various technologies
available for diagnosis of brain tumor, MRI is the preferred technology which enables the
diagnosis and evaluation of brain tumor. The current work presents various clustering
techniques that are employed to detect brain tumor. The classification involves classification
of images into normal and malformed (if detected the tumor). The algorithm deals with
steps such as preprocessing, segmentation, feature extraction and classification of MR brain
images. Finally, the confirmatory step is specifying the tumor area by technique called
region of interest.
A deep convolutional structure-based approach for accurate recognition of ski...IJECEIAES
One-third of all cancer diagnoses worldwide are skin malignancies. One of the most common tumors, skin cancer can develop from a variety of dermatological conditions and is subdivided into different categories based on its textile, color, body, and other morphological characteristics. The most effective strategy to lower the mortality rate of melanoma is early identification because skin cancer incidence has been on the rise recently. In order to categorize dermoscopy images into the four diagnosis classifications of melanoma, benign, malignant, and human against machine (HAM) not melanoma, this research suggests a computer-aided diagnosis (CAD) system. Experimental results show that the suggested approach enabled 97.25% classification accuracy. In order to automate the identification of skin cancer and expedite the diagnosis process in order to save a life, the proposed technique offers a less complex and cutting-edge framework.

MALIGNANT AND BENIGN BRAIN TUMOR SEGMENTATION AND CLASSIFICATION USING SVM WI...sipij
In this article a method is proposed for segmentation and classification of benign and malignant tumor slices in brain Computed Tomography (CT) images. In this study image noises are removed using median and wiener filter and brain tumors are segmented using Support Vector Machine (SVM). Then a two-level discrete wavelet decomposition of tumor image is performed and the approximation at the second level is obtained to replace the original image to be used for texture analysis. Here, 17 features are extracted that 6 of them are selected using Student’s t-test. Dominant gray level run length and gray level co-occurrence texture features are used for SVM training. Malignant and benign tumors are classified using SVM with kernel width and Weighted kernel width (WSVM) and k-Nearest Neighbors (k-NN) classifier. Classification accuracy of classifiers are evaluated using 10 fold cross validation method. The segmentation results are
also compared with the experienced radiologist ground truth. The experimental results show that the proposed WSVM classifier is able to achieve high classification accuracy effectiveness as measured by sensitivity and specificity.
An Efficient Brain Tumor Detection Algorithm based on Segmentation for MRI Sy...ijtsrd
A collection, or mass, of abnormal cells in the brain is called as Brain Tumor . The skull, which encloses your brain, is very rigid. Growth inside such a restricted space can cause problems. Brain tumors can be malignant or benign. Segmentation in magnetic resonance imaging (MRI) was an emergent research area in the field of medical imaging system.

This document summarizes a research paper that examines pricing strategy in a two-stage supply chain consisting of a supplier and retailer. The supplier offers a credit period to the retailer, who then offers credit to customers. A mathematical model is formulated to maximize total profit for the integrated supply chain system. The model considers three cases based on the relative lengths of the credit periods offered at each stage. Equations are developed to represent the profit functions for the supplier, retailer and overall system in each case. The goal is to determine the optimal selling price that maximizes total integrated profit.
This document summarizes various techniques for image segmentation that have been studied and proposed in previous research. It discusses edge-based, threshold-based, region-based, clustering-based, and other common segmentation methods. It also reviews applications of segmentation in medical imaging, plant disease detection, and other fields. While no single technique can segment all images perfectly, hybrid and adaptive methods combining multiple approaches may provide better results. Overall, image segmentation remains an important but challenging task in digital image processing and computer vision.
This document presents a test for detecting a single upper outlier in a sample from a Johnson SB distribution when the parameters of the distribution are unknown. The test statistic proposed is based on maximum likelihood estimates of the four parameters (location, scale, and two shape) of the Johnson SB distribution. Critical values of the test statistic are obtained through simulation for different sample sizes. The performance of the test is investigated through simulation, showing it performs well at detecting outliers when the contaminant observation represents a large shift from the original distribution parameters. An example application to census data is also provided.

Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the

Abstract— Skin malignant growth is the most widely
recognized, everything being equal. Between 40 to 50 percent of
all disease cases analyzed each year are skin malignant growth.
Melanomas represent just four percent of all skin malignant
growth cases yet are undeniably more perilous. Of all skin
disease-related passing’s, 79 percent are from melanoma. Skin
disease can be relieved if distinguished early. To appropriately
distinguish melanoma, there is a need for a skin test. This is an
obtrusive method and is the reason there is a requirement of a
conclusion framework that can annihilate the skin test strategy
emerges. We proposed to build up a Computer-Aided System
that is equipped for ordering a skin injury as threatening or
favorable by utilizing the ABCD rule which represents
Asymmetry, Border, Color, Diameter of the skin sore. Further,
the preprocessed pictures are portioned and commotions are
taken out from the Dermoscopic pictures for instance hair and
air bubbles. Also, finally, by utilizing a classifier, the proposed
system identifies the pictures as favorable or harmful.

I. INTRODUCTION
Skin malignancy is a deadly infection such as reality
undermining. As of late, skin disease has gotten perhaps the
deadliest types of malignancies found in individuals. Out of the
relative multitude of different kinds of skin malignancies,
melanoma tumors are the most generally perceived kind of skin
illness and are the most unconventional in the world. Melanoma
skin cancer has become so unsafe that it is growing in many
numbers among people and causing unhealthiness to them.
Melanoma also referred to as malignant melanoma, is a result of
variation between the cells from pigments that give color to our
body. This disease may arise from a mole and it may give rise to

some changes such as an increment for dimension, Irregular
boundary, and a change in shading, skin damage, or bothering.
Doctors say that the unveiling of the body to the sun as in the
UV radiations or tanning beds for a longer duration causes harm
to the DNA of our skin cells, which disturbs their normal
function and makes them grow uncontrollably. Melanoma skin
cancer is so harmful that if not detected at an early stage it could
spread to the whole body, and can be the cause of a patient’s
death. It is perhaps the most capricious skin malignancies and
hence identification of melanoma disease at the beginning
phases could help in restoring it rapidly and proficiently. The
difference between a benign and malignant sore can be found
using ABCD (Asymmetric, Border irregularity, Color,
Diameter) rule. A benign melanoma infrequently spreads in the
body. Examples of benign melanoma are a mole or a birthmark.
Malignant melanomas are irregular in shape, have no symmetry,
there is no specific color to be determined.
II. LITERATURE SURVEY
A worldwide temperature alteration has expanded the force of
solar radiation which has prompted ascending of skin melanoma
malignant growth in individuals. Melanoma can be relieved on
the off chance that it is distinguished in the beginning phases.
The conventional way to deal with melanoma skin malignant
growth discovery requires a biopsy, an obtrusive strategy that
can be an excruciating, expensive and late process. Along these
lines, the need for a computerized system that can identify
melanoma cancer precisely is a need in the clinical domain.
Melanoma scan exists in fluctuated forms, shadings, and
dimensions which makes it difficult for identifying cancer at the
beginning phase which is the reason it is fundamental to plan a
framework that considers appropriate highlights for extraction.
Analysis of skin melanoma cancer utilizing a mechanized
framework incorporates the following steps:
● 1st Step: - Image Acquisition: Collection of
Dermoscopic image datasets
● 2nd Step: - Image Preprocessing: Removal of noises
and distortions from the input images.
● 3rd Step: - Image Segmentation: Segmenting
preprocessed images from infected and non-infected
portions.
● 4th Step: - Feature Extraction: Extrication of nine
features established from the ABCD rule.

2. ○ A- Asymmetry: Malignant sores are asymmetric in shape.
○ B- Border: Malignant sores have irregular borders.
○ C- Color: A malignant sore usually consists of black,
white, red, blue, or brown tones.
○ D- Diameter: A malignant sore is often bigger than 6 mm
in diameter.
● 5th Step:- Classification: Skin sore is classified into two
categories, benign and malignant.
[3] S. mane et al. proposed a framework where the original
shading skin picture is chosen from the dataset. Chosen original
shading skin picture is changed over into a grey shading picture.
The skin picture contains a few hairs which will corrupt the
precision of characterization. So, hair expulsion is finished by
utilizing the Gaussian channel. The hair eliminated picture
contains the sore part alongside the sound part. For acquiring
just, the sore part segmentation is performed. In the subsequent
stage, highlights are extricated from the divided sore. In feature
extraction, all 10 features are extricated in which edge, zone,
anomaly, contrast, relationship, energy, homogeneity, and
shading are the features. These features are given to the SVM
classifier [3]. Results are gotten utilizing shading, shape, and
surface highlights. Sensitivity, specificity, and accuracy are
registered by utilizing an SVM classifier. It is seen that the SVM
linear function gives [3] greater affectability and precision than
the SVM RBF kernel. If there should arise an occurrence of
explicitness SVM RBF kernel performs better compared to
SVM linear function [3].
[4] S. Majumder, et. al proposed a framework that
considered more features from the essential ABCD rule. It takes
200, 8-digit RGB color Dermoscopic pictures with a resolution
of 768560 as an input dataset, containing 160 4 favorable and 40
harmful melanomas. These images were taken from a PH2
dataset which contains skin sores of every single distinctive
shape, tone, and size. Image resizing and contrast change were
the steps involved with image preprocessing. To reduce noises
like hair or air bubbles from the Dermoscopic images an RGB
filter is applied to the images to clear the view. Otsu’s
thresholding method was used to segment the images and after
this work, a concealing effect is applied to reduce mass from the
images. The feature extricated is established from the ABCD
rule of Dermoscopic and also Backpropagation Neural Network
(BNN)is used to classify the uploaded picture as a benign sore
or malignant sore [4].
[5] K. Eltayef, et. al also proposed a framework that
zeroed in on different image pre-processing and image
segmentation strategies [5]. In image pre-processing step it
included two key activities: hairs, reflection artifact detection,
and removal [5]. To distinguish any noise like air bubbles, a
straightforward threshold method is applied. A bank of 64
directional filters has been utilized to play out hair detection [5].
The picture is filtered by each directional filter with various
parameters and the distinction of Gaussians is utilized by
tracking down the nearest greatest at every pixel area [5]. In this
way, the threshold method is applied to arrange every pixel as
one or the other hair or background [5]. After reflection artifacts
and hairs are identified, their binary conceals are increased by
greyscale pictures. This framework utilized a two-venture
division: Markov Random Field (MRF) and Fuzzy c-means
(FCM)[5].
[6] O. Murumkar et al. proposes a system consisting
mainly of 2 components a. Image segmentation b. Feature
Extraction. Thresholding, edge-based, and region-based
methods are used to perform image segmentation; also the
proposed framework comprises Otsu's division strategy [6]. The
feature extricated is established from the ABCD rule of
Dermoscopic[6]. The ABCD represents Asymmetry, Border
structure, Color variety, and Diameter of the sore. In the second
period of feature extraction, four highlights (Asymmetry,
Border, Color Variation, and Diameter) are separated [6]. By
utilizing the beneath equation for the figuring of Total
Dermoscopic Value (TDV), the value TDV is resolved. On the
off chance that TDV discovers to be > 5.45, Melanoma sore
disease is identified [6].
[7] H. Mhaske et al. took 150 pictures from online sources
and division is performed. In the Thresholding technique peak
value for the skin and peak value for the sore is resolved and
afterward limit is chosen in the middle of these two peak points
[7]. The pixel intensity values that are more prominent than the
threshold value is set as 0 while intensity values that are not as
much as the threshold value are set as 1[7]. For segmentation of
skin malignant growth pictures region growing and merging
techniques is utilized. Feature extraction is finished utilizing
two wavelets [7]. An original picture is isolated into four
sections from the outset level of decomposition. Each part
addresses the feature and two degrees of decomposition are
done to get the highlights [7]. In the second degree of
decomposition out of four sections again each part is separated
into four sections so complete 16 sections are created [7]. And
afterward, high pass and low pass filters are applied to the
picture. The features are gotten utilizing boundaries like mean,
median, standard deviation, minimum, variance, and maximum
[7]. Classification of pictures into malignant growth type and
skin type or non-disease type is finished supervised and
unsupervised learning [7]. Neural Network classifier, k-means
clustering algorithm, and SVM(Support Vector Machine) are
utilized to order the sores[7].
[9] M. A. Sheha, et. al encouraged a framework that
utilizes surface examination that disposes of the segmentation
step [9]. It had a total of 102 dermoscopy images dataset which
comprised of 51 images of each benign and malignant
melanoma on which picture resizing is applied of 512⤫512[9].
Also, the transformation from RGB to a grey level where the
features are dependent on the grey level co-occurrence matrix is
done [9]. The features separated are as per the following:
Correlation, Contrast, Cluster Prominence, Homogeneity,
Dissimilarity, Difference entropy, Difference variance,
Information measure of correlation, Information measure of
correlation, Inverse difference homogenous, Inverse difference
moment normalized, and Inverse difference normalized.
Multilayer Perceptron (MLP) is used to classify them afterward
[9].
[10] A. G. Isasi, et. al put forward diverse pattern’s
recognition algorithms dependent on the idea of skin disease
[10]. Three features which are reticulated, globular, and blue
pigmentation are Identified as these occur repetitively in
harmful melanoma skin cancer [10]. These features are
extricated from pattern recognition algorithms [10].

Figure 1: Flow Diagram
01. Image Acquisition
The Ph2 database is a freely accessible data set of
Dermoscopic images given by Pedro Hispano Hospital.
From this data set, 200 melanocytic images were
gathered which comprises 160 favorable and 40 harmful
sores.
02. Image Pre-processing
Before extracting features and classifying the images as
benign or malignant the images are first pre-processed
so that the noise like air bubbles and hair are removed
from the image to get a clear image for segmentation
purposes. First colored images are converted into
grayscale images than to increase the efficiency of the
system, the morphological operation is applied to the
images. After morphological filtering is done blackhat
filtering is applied on the images to enhance the
darkened areas of the images to focus on. At last, an
inpainting algorithm is used to reduce the hair visibility
from the images by highlighting the part which has hair
contours. It helps in restoring the background of the
image without hairs.
03. Image Segmentation
Segmentation is carried out to separate the region of
interest, basically the infected portion from the
uninfected portion of the skin sore. Here, for
segmentation mainly two algorithms are used (a) Otsu’s
thresholding method (b) Chan-vase model. Otsu’s
thresholding method separates the background from
foreground pixels into different classes by using the
bi-modal histogram. And using this image as input to
Chan-vase, it uses a contour model which separates the
foreground and background once it reaches the border.
04. Feature extraction
After image preprocessing and segmentation, we extract
appropriate features from the images. Using the ABCD
rule, we continue to extract 9 features from the images.
a. Asymmetry
In malignant sores usually, sores are not symmetrical.
Here we calculate to seek out if bisection of the sore is
symmetric to the opposite bisection of the sore or not.
For calculating this, the image is aligned with the
euclidean system, and the center of the segmented
picture is taken as the center of the reference system.
Now, the image is rotated so that its x-axis aligns with
the larger axis of the coordinate system. Further, the
image is flipped along the x-axis. The difference
between these two provides the well-separated region
along the x-axis. Similarly, calculated with the y-axis.
b. Border
The contour of the blob is defined by the border. A
malignant sore has a highly irregular shape and no
visible border to be defined. Here the area is to outer
edge ratio, density index, and the multiplication product
of area and outer edge are calculated to calculate B1,
B2, and B3 respectively. B1 values are rather small, B2
determines the felicity of the edges and spans from one
to zero and B3 values are bigger.
c. Colour
The segmented image is applied as a conceal on the
colored image as a result we get an RGB colored
segmented image. The RGB threshold values are
calculated for dark brown, black, light brown, red,
white, and blue-grey colors from the picture and the
picture is then converted into an HSV color space. Each
color is used as a conceal. On the HSV image bitwise
AND operation is carried out to find the color conceal
and the live contours. If the live contour value is larger
than 0 then the color is present or else not. The color
score spans from 1 to 6 as there are 6 colors supposed to
be there in the skin sore.
d. Diameter
Malignant melanoma may have a diameter larger than
or equal to 6 mm. D1- an average of the diameters of
the sore, D2 - the difference between the smaller and
larger axis, D3- diameter of the sore. is calculated.
05. Classification
After extracting the 9 features from the segmented
images it is time to classify them. Here we use a
sequential artificial network. Adam classifier is applied
to classify them as benign or malignant. First, some
sample dataset from the dataset available is fetched as
input to the model as training data to train the model.
After the model is trained, the remaining dataset is
fetched as testing data to the model to predict the sore as
malignant or benign. In this way, the model is trained

and the system detects melanoma skin cancer
efficiently.
IV. CONCLUSION
The escalating rise in melanoma skin cancer patients is a very
serious issue to be noted. This issue is grave because
melanoma is one of the skin cancers which can spread to
other skin cells nearby and can escalate at a very high speed
sometimes causing the death of the patient. If this cancer is
detected at an early stage, then it can be cured. The
conventional methods used to detect melanoma are very
expensive and painful. So, for this reason, there is a demand
for a computerized system that can effectively detect
melanoma at an early stage by evaluating the Dermoscopic
image of the sore. Our proposed system proposes to do alike
by using 6 steps in general on the Dermoscopic image dataset
PH2 which is publicly available. The six steps are image
acquisition, image preprocessing, image segmentation,
feature extraction, Image classification, and final output. Our
system uses a neural network and machine learning
algorithms to detect melanoma at an early stage. Although,
there are some regions in this study that are to be identified
and taken into consideration. One of them is that
dark-colored people’s sore images are difficult to be
segmented and extrication of features is also a difficult task.
To increase the efficiency of the system we would like to add
more real-time datasets from hospitals that detect melanoma
by conventional methods.
