This document describes research on algorithms for recognizing ear tags for biometric identification. It presents three algorithms: 1) using discrete cosine transformation to distinguish ear image characteristics, which achieved 86% accuracy; 2) using principal component analysis of ear images, which achieved 89% accuracy; and 3) segmenting ear images into static marks, which achieved the best result of 92% accuracy with 12 marks. The discrete cosine method was less accurate due to extracting too many characteristics, while the principal component and segmentation methods performed better with fewer extracted characteristics.
FUSION BASED MULTIMODAL AUTHENTICATION IN BIOMETRICS USING CONTEXT-SENSITIVE ...cscpconf
Biometrics is one of the primary key concepts of real application domains such as aadhar card, passport, pan card, etc. In such applications user can provide two to three biometrics patterns
like face, finger, palm, signature, iris data, and so on. We considered face and finger patterns
for encoding and then also for verification. Using this data we proposed a novel model for
authentication in multimodal biometrics often called Context-Sensitive Exponent Associative Memory Model (CSEAM). It provides different stages of security for biometrics patterns. In
stage 1, face and finger patterns can be fusion through Principal Component Analysis (PCA), in stage 2 by applying SVD decomposition to generate keys from the fusion data and preprocessed face pattern and then in stage 3, using CSEAM model the generated keys can be encoded. The final key will be stored in the smart cards. In CSEAM model, exponential
kronecker product plays a critical role for encoding and also for verification to verify the chosen samples from the users. This paper discusses by considering realistic biometric data in
terms of time and space

An Iot Based Smart Manifold Attendance SystemIJERDJOURNAL
ABSTRACT:- Attendance has been an age old procedure employed in different disciplines of educational institutions. While attendance systems have witnessed growth right from manual techniques to biometrics, plight of taking attendance is undeniable. In fingerprint based attendance monitoring, if fingers get roughed / scratched, it leads to misreading. Also for face recognition, students will have to make a queue and each one will have to wait until their face gets recognised. Our proposed system is employing “manifold attendance” that means employing passive attendance, where at a time, the attendance of multiple people can get captured. We have eliminated the need of queue system / paper-pen system of attendance, and just with a single click the attendance is not only captured, but monitored as well, that too without any human intervention. In the proposed system, creation of database and face detection is done by using the concepts of bounding box, whereas for face recognition we employ histogram equalization and matching technique.

Facial Emotion Recognition using Convolution Neural NetworkYogeshIJTSRD
Facial expression plays a major role in every aspect of human life for communication. It has been a boon for the research in facial emotion with the systems that give rise to the terminology of human computer interaction in real life. Humans socially interact with each other via emotions. In this research paper, we have proposed an approach of building a system that recognizes facial emotion using a Convolutional Neural Network CNN which is one of the most popular Neural Network available. It is said to be a pattern recognition Neural Network. Convolutional Neural Network reduces the dimension for large resolution images and not losing the quality and giving a prediction output whats expected and capturing of the facial expressions even in odd angles makes it stand different from other models also i.e. it works well for non frontal images. But unfortunately, CNN based detector is computationally heavy and is a challenge for using CNN for a video as an input. We will implement a facial emotion recognition system using a Convolutional Neural Network using a dataset. Our system will predict the output based on the input given to it. This system can be useful for sentimental analysis, can be used for clinical practices, can be useful for getting a persons review on a certain product, and many more.

Matching Sketches with Digital Face Images using MCWLD and Image Moment Invar...iosrjce
Face recognition is an important problem in many application domains. Matching sketches with
digital face image is important in solving crimes and capturing criminals. It is a computer application for
automatically identifying a person from a still image. Law enforcement agencies are progressively using
composite sketches and forensic sketches for catching the criminals. This paper presents two algorithms that
efficiently retrieve the matched results. First method uses multiscale circular Weber’s local descriptor to encode
more discriminative local micro patterns from local regions. Second method uses image moments, it extracts
discriminative shape, orientation, and texture features from local regions of a face. The discriminating
information from both sketch and digital image is compared using appropriate distance measure. The
contributions of this research paper are: i) Comparison of multiscale circular Weber’s local descriptor with
image moment for matching sketch to digital image, ii) Analysis of these algorithms on viewed face sketch,
forensic face sketch and composite face sketch databases

We will implement a facial emotion recognition system using a Convolutional Neural Network using a dataset. Our system will predict the output based on the input given to it. This system can be useful for sentimental analysis, can be used for clinical practices, can be useful for getting a persons review on a certain product, and many more.

Matching Sketches with Digital Face Images using MCWLD and Image Moment Invar...iosrjce
Face recognition is an important problem in many application domains. Matching sketches with
digital face image is important in solving crimes and capturing criminals. It is a computer application for
automatically identifying a person from a still image. Law enforcement agencies are progressively using
composite sketches and forensic sketches for catching the criminals. This paper presents two algorithms that
efficiently retrieve the matched results. First method uses multiscale circular Weber’s local descriptor to encode
more discriminative local micro patterns from local regions. Second method uses image moments, it extracts
discriminative shape, orientation, and texture features from local regions of a face. The discriminating
information from both sketch and digital image is compared using appropriate distance measure. The
contributions of this research paper are: i) Comparison of multiscale circular Weber’s local descriptor with
image moment for matching sketch to digital image, ii) Analysis of these algorithms on viewed face sketch,
forensic face sketch and composite face sketch databases

A hybrid approach for face recognition using a convolutional neural network c...IAESIJAI
Facial recognition technology has been used in many fields such as security,
biometric identification, robotics, video surveillance, health, and commerce
due to its ease of implementation and minimal data processing time.
However, this technology is influenced by the presence of variations such as
pose, lighting, or occlusion. In this paper, we propose a new approach to
improve the accuracy rate of face recognition in the presence of variation or
occlusion, by combining feature extraction with a histogram of oriented
gradient (HOG), scale invariant feature transform (SIFT), Gabor, and the
Canny contour detector techniques, as well as a convolutional neural
network (CNN) architecture, tested with several combinations of the
activation function used (Softmax and Segmoïd) and the optimization
algorithm used during training (adam, Adamax, RMSprop, and stochastic
gradient descent (SGD)). For this, a preprocessing was performed on two
databases of our database of faces (ORL) and Sheffield faces used, then we
perform a feature extraction operation with the mentioned techniques and
then pass them to our used CNN architecture. The results of our simulations
show a high performance of the SIFT+CNN combination, in the case of the
presence of variations with an accuracy rate up to 100%.
