This document introduces color models and discusses RGB and CMY color models. It provides an overview of the primary colors and color mixing properties of each model. RGB is an additive model that uses red, green, and blue light to create colors and is used for displays. CMY is a subtractive model that uses cyan, magenta, and yellow inks to create colors by absorbing light and is used for printing. Each model has different applications and advantages for displays versus printed materials.
The RGB and CMY color models are two primary systems for representing color digitally. The RGB model uses additive color mixing of red, green, and blue light to reproduce a wide gamut of colors on computer screens. It is well-suited for digital imaging.

This document provides an overview of different color models, including RGB, CMYK, and HSV models. It explains that RGB is an additive color model used for computer displays where colors result from transmitted light. CMYK is a subtractive color model used in printing, where colors are the result of reflected light. It describes the primary colors that make up each model - red, green, blue in RGB and cyan, magenta, yellow, and black in CMYK. The document also introduces the HSV color model which describes colors in terms of hue, saturation, and value.
The HSV color model defines color space using three components: hue, saturation, and value. Hue represents the color, defined as an angle from 0-360 degrees and correlates to colors like red, yellow, green, etc. Saturation indicates the amount of gray in a color, ranging from 0% (gray) to 100% (vibrant color). Value represents the brightness level from 0% (black) to 100% (full brightness). The HSV color space is widely used in computer graphics and image editing to select and manipulate colors.
This document discusses different types of images used in multimedia. It describes bitmapped images, which are composed of pixels and have attributes like resolution and color depth that determine file size. Vector images are composed of graphic primitives defined by mathematical equations and can be resized without quality loss. The document outlines popular file formats for bitmaps and vectors as well as software used to create and edit different image types. Hardware and file conversion are also mentioned.
Color is a sensation produced by the human visual system. The two most common color models are RGB, used for computer displays, and CMYK, used for printing. RGB is an additive model that uses combinations of red, green, and blue light to produce colors. CMYK is a subtractive model that uses combinations of cyan, magenta, yellow, and black inks to produce colors. Both models represent colors using three numeric values corresponding to the intensities of the primary colors.
Texture mapping is a common method to add surface detail by mapping texture patterns onto object surfaces. The texture can be defined as a rectangular array or a procedure modifying surface intensity values. This approach, called texture mapping or pattern mapping, was illustrated by mapping a unit square pattern to a cylindrical surface through a series of linear transformations. Pixel positions were mapped to texture space and averaged to obtain each pixel intensity from the texture pattern.

The future of computational photography includes higher resolution mobile images through new algorithms, more compact programmable flashes, and continued research into better editing tools.
Graphic Design - History of Graphic DesignJamie Hutt
This document provides a history of graphic design from pre-historic art to modern design. It discusses early graphic design beginning with printed materials like books, magazines, and newspapers produced on printing presses. It mentions Piet Mondrian's influence through use of grids and the transition to electronic graphic design with computers. The Bauhaus art and architecture school is described as teaching simplified, functional, and mass-produced design. Important founders of modern design like László Moholy-Nagy and El Lissitzky are noted. The document concludes with the emergence of corporate identity/logo design through Paul Rand and graphic design education today. Students are assigned a project to present on a famous graphic designer.
The document discusses various techniques for image compression including:
- Run-length coding which encodes repeating pixel values and their lengths.
- Difference coding which encodes the differences between pixel values.
- Block truncation coding which divides images into blocks and assigns codewords.
- Predictive coding which predicts pixel values from neighbors and encodes differences.
Reversible compression allows exact reconstruction while lossy compression sacrifices some information for higher compression but images remain visually similar. Combining techniques can achieve even higher compression ratios.
The document discusses basic relationships between pixels in digital images. It defines that a pixel has 4 horizontal and vertical neighbors, called 4-neighbors. It also has 4 diagonal neighbors, and together with the 4-neighbors they form the 8-neighbors of a pixel. Adjacency between pixels is defined based on 4, 8 or m-connectivity depending on pixel intensity values. Connectivity and paths between pixels are also described. Regions in an image are defined as connected subsets of pixels, and region boundaries are pixels adjacent to the complement of the region.

It discusses that RGB uses red, green, and blue primary colors in an additive model, and is used for computer and television screens. CMY uses cyan, magenta, and yellow in a subtractive model, where inks subtract brightness from white. It is used for color printing. Examples of each color model are also presented.
Color image processing involves working with images that contain color information. There are two main types: full-color processing of images from color cameras or scanners, and pseudocolor processing which assigns a color to grayscale values. Color is described using properties like hue, saturation and brightness. Common color models for image processing include RGB, CMY, and HSI. RGB represents colors as combinations of red, green and blue primary colors. CMY uses cyan, magenta and yellow pigment primaries for printing. HSI separates intensity from hue and saturation, making it useful for color image algorithms.
The RGB color model uses additive color mixing of red, green, and blue light to produce various colors. It is the model used for color displays like computer and TV screens. The RGB color space is represented as a cube with red, green, and blue forming the axes and varying levels of each component from 0 to 1 producing different colors that combine to make white at maximum values. This model directly reflects how true color displays produce colors and is used for computer graphics and digital images but not print production which uses the CMYK subtractive color model.
Differences between rgb and cmyk color schemesDhanasekar181
The document discusses the differences between the RGB and CMYK color schemes. RGB uses red, green, and blue as primary colors and is an additive color model used for digital screens. CMYK uses cyan, magenta, yellow, and black inks as primary colors and is a subtractive color model used for printed materials. The key differences are that RGB is for digital works and has a wider color range while CMYK is for print and has less vibrant colors due to subtractive color mixing.
A color model is a system that creates a full range of colors from a small set of primary colors. There are two main types of color models: additive and subtractive. Additive color models like RGB use light to display colors on screens by combining red, green, and blue light, starting with black and ending with white. Subtractive color models like CMYK use pigments to print colors, starting with white and ending with black by combining cyan, magenta, yellow, and black inks. RGB is used for digital displays while CMYK is used for print because it reflects how inks absorb and reflect light.
The document discusses color image processing and color models. It provides information on several topics:
- Color images can be characterized using a three-dimensional color space model. Common color models for different applications include RGB, CMYK, and HSI.
- Digital image processing techniques allow for objective measurement and analysis of image properties compared to manual interpretation.
- Common color models are RGB for monitors/video, CMYK for printing, and color features can be used for applications like face recognition.
- A color model represents colors as sets of numbers in a coordinate system. Models discussed include RGB, CMYK, and RYB. CMYK uses percentages of cyan, magenta, yellow and black in
A color model specifies a color space and visible subset of colors within it. There are four main hardware-oriented color models: RGB, CMY, CMYK, and YIQ. However, these are not intuitive for describing color in terms of hue, saturation and brightness. Therefore, models like HSV, HLS, and HVC were developed which relate more directly to human perception of color. The RGB and CMY models represent colors as combinations of red, green, blue and cyan, magenta, yellow primary colors respectively and are used in monitors and printing.
This document provides an overview of colour theory and models for application in multimedia. It describes how colour is perceived and named, then covers the RGB, CMYK, and HSV colour models.

Elements of graphics such as lines, shapes, color and texture are also summarized.
Elem of design unit 2 module 1 discussion of digital colorkateridrex
There are two color modes used in design - RGB for digital screens and CMYK for print. RGB stands for red, green, and blue and is additive, meaning combining the colors makes white. CMYK stands for cyan, magenta, yellow, and black and is subtractive, where combining two colors subtracts the third to make other hues. Designers need to be aware of the difference between RGB and CMYK since the colors will appear differently in print versus on screen.
1. Monitors use additive color (RGB) to display millions of colors by mixing light, while printers use subtractive color (CMYK) to reproduce thousands of colors by overlaying inks.
2. ICC profiles are used to linearize and calibrate devices to help predict printed output and ensure accurate color representation across different devices.
3. Factors like ink, paper, lighting, and calibration affect color reproduction, so profiling monitors and printers is important for consistency between screens and printed materials.
1. The document discusses various color models including RGB, CMY(K), HSV, HSL, and YIQ color models.
2. It describes the key components and properties of each color model such as hue, saturation, brightness. For example, RGB is an additive color model where primary colors are combined with light, while CMY(K) is a subtractive model used in printing.
3. Different color models have different applications based on their properties. For example, RGB is used for computer graphics and image processing while CMY(K) is used for printing and YIQ is used for television broadcasting.
This document discusses various color models used in computer graphics including RGB, HSV, HSL, CMY, and CMYK. It explains the key components of each model such as hue, saturation, value, and how colors are represented. Common applications of different color models are also summarized such as RGB for computer displays and CMYK for printing. In addition, the concepts of dithering and half-toning techniques used to reproduce colors on devices are introduced.
Lesson 6 discusses images in multimedia. It covers creating still images using bitmaps or vector graphics. Bitmaps use pixels to represent images while vector graphics use mathematical formulas. The document also discusses color models like RGB and HSB. Color palettes define the available colors and dithering is used to match colors. Common file formats for images on different platforms are also presented.
Images are an important element in multimedia. There are two main types of images: bitmaps, which use pixels to represent color information, and vector images, which use mathematical coordinates. Various tools can be used to create and edit images, including bitmap software, 3D modeling programs, and image capture and editing features. Color is a key aspect, with different color models and palettes used depending on the intended display and use of the images.
1. A color gamut refers to the range of colors that can be displayed or printed using a particular color system. The human eye can see a wider range of colors than any reproduction method.
2. The RGB gamut is the subset of colors that can be displayed on computer or TV monitors using red, green and blue light, though some colors like pure cyan or yellow cannot be accurately shown.
3. The CMYK gamut used in printing has an even smaller color range than RGB and uses cyan, magenta, yellow and black inks, with any colors outside this gamut called out-of-gamut colors.

1. The system will manage student, subject, and marks information for classes 6-10 and generate tabulation sheets. It will also maintain the institute website.
2. The background discusses similar existing systems used in education sectors.
3. Performance will be evaluated based on user interfaces, validity checks, and software attributes like security, maintainability and portability.
The system aims to simplify and speed up the result preparation and management process for educational institutes.
This document discusses routing protocols in computer networks. It defines distance vector routing and link state routing, describing how each determines the best path. Distance vector routing uses hop count as a metric and shares routing tables, while link state routing shares information about network reachability and metrics. The document provides examples of how distance vector and Dijkstra's algorithm work through updating routing tables. It outlines characteristics of routers and compares advantages and disadvantages of the two routing approaches.
The document provides information about different generations of computers. It discusses Babbage's Analytical Engine as an early predecessor to modern computers. The first generation used vacuum tubes and were large, expensive machines. The second generation used transistors, making computers smaller, cheaper, and more reliable. The third generation used integrated circuits, making computers even smaller and faster. Later generations incorporated microprocessors, leading to the development of personal computers. The document also discusses some examples of specific early computers like the IAS and IBM 360.
This document discusses semiconductors and provides details about their properties and characteristics. It defines a semiconductor as a material with resistivity between that of a conductor and insulator. Some key points made in the document are:
- Semiconductors have properties like negative temperature coefficient of resistance and their conductivity can change when doped with impurities.
- Common semiconductors include silicon and germanium which form covalent bonds and have small energy gaps between valence and conduction bands.
- Semiconductors can be doped as n-type or p-type to introduce free electrons or holes that serve as majority carriers for current flow. A pn junction is formed when a p-type and n-
This document provides an introduction to the Open Systems Interconnection (OSI) model, which defines seven layers of network architecture: Physical, Data Link, Network, Transport, Session, Presentation, and Application. It describes each layer's responsibilities in moving data from one node or process to another. The Physical layer moves individual bits, the Data Link layer moves frames between nodes, the Network layer moves packets between hosts, the Transport layer moves segments between processes, and so on up to the Application layer which provides user-level services. An illustration is included showing how data is encapsulated and moves through each layer in an exchange between two systems.
The presentation topic is on computational models. It will be presented by Md. Touhidur Rahman. The document discusses four computational models: finite automata (DFA and NFA), context free grammar, pushdown automata, and Turing machines. Finite automata are defined using states, symbols, transitions, a start state, and accepting states. Context free grammars are defined using variables, terminals, productions, and a start symbol. Pushdown automata extend NFAs with a stack. Turing machines are formally defined but also described at a higher level for understanding.
This document contains examples of different types of tabular data presentations:
- Univariate tables use one variable to organize data into rows and columns, such as user numbers for different mobile operators.
- Bivariate tables use two variables, like the number of rich and middle class cellphone users of different brands.
- Multivariate tables use two or more variables, for example semester-wise results for students organized by department, age group, and school board performance.
Tabular presentations clearly organize data without losing information, and are useful for database design, cascading style sheets, Excel sheets, and representing data in word documents.
This document discusses production costs from the perspective of a group presenting on the topic. It defines costs and production costs, outlines the main types of costs including fixed, variable, average and marginal costs. It provides examples and formulas to calculate these different costs. The document also discusses elements that make up production costs, the relationship between different cost curves, how to estimate costs, and provides a summary of how costs and profits are considered from an economic and accounting perspective.

Networking is a telecommunications network that allows computers to exchange data. In
computer networks, networked computing devices pass data to each other along data
connections. Data is transferred in the form of packets. The connections between nodes are
established using either cable media or wireless media.
3. WHAT IS COLOR?
Color is a sensation produced by the human eye and
nervous system.
4. COLOR MODELS
Color model is an orderly system for creating a whole ranges
of color from a small set of primary color.
A color model is also a way to turn colors into numbers with
a mathematical formula.
7. ADDITIVE COLOR MODEL……..
Additive color is color created by mixing a
number of different light colors, with shades
of red, green, and blue.
Example of additive color model is RGB
Model
RGB model contains primary colors.
primary colors are:
Red
Green
Blue
8. SUBTRACTIVE COLOR MODEL……..
A subtractive color model explains the
mixing of a limited set of paint pigments to
create a wider range of colors.
Example of subtractive color model is CMY
Model.
CMY model contain secondary color.
Secondary colors are:
Red + Blue =Magenta
Green +Blue = Cyan
Red + Green = Yellow
10. PROPERTIES OF RGB COLOR
SYSTEM……
* Additive color model.
* For computer displays.
* Uses light to display color.
* Colors result from transmitted light.
* Red + Green + Blue = White.
11. RGB REPRESENTATION……
We can imagine the RGB as a 3-dimensions .
RGB is our Goal from
Now to the end.
Actually RGB is three
layers behind each
other but just for
imagining .
12. RGB COLOR MODEL……..
The RGB Color Model
If R,G, and B are represented with 8 bits (24-bit RGB
image), the total number of colors is (28 )3=16,777,216
16. IMPORTANCE OF RGB COLOR
MODEL……
The color model RGB is used in hardware applications
like PC monitors, cameras and scanners,
It is used for Web graphics, but it cannot be used for
print production.
It directly reflects the physical properties of "True-
color" displays
17. APPLICATIONS OF RGB COLOR
MODEL……
It is used—
For sensory representation
Display of text images in electronic
system,
For example-Computer, T.V., Camera
19. PROPERTIES OF CMY(K) COLOR
MODEL…….
* Subtractive color model.
* For printed material.
* Uses ink to display color.
* Colors result from reflected light.
* Cyan + Magenta + Yellow = Black.
20. CMY(K) MODEL…….
•Unit Cube defined on C, M & Y axes.
•A printed color that looks red absorbs
the other two components G and B and
reflects R.
•Thus the C-M-Y coordinates are just
the complements of the R-G-B
coordinates.
21. CONTINUE…….
In additive color models such as RGB, white is the “additive” combination
of all primary colored lights, while black is the absence of light.
In the CMYK model, it is the opposite: white is the natural color of the
paper or other background, while black results from a full combination of
colored inks.

24. IMPORTANCE OF CMY COLOR
MODEL…….
the CMY color model is used in color printers.
It is created by the subtractive mode
Used in most commercial color printing (books,
magazines, etc.)
25. APPLICATIONS OF CMY COLOR
MODEL…….
Used for hardcopy devices
Used to describe the printing process
Used in color printing
26. RGB VS. CMY MODEL…….
RGB is based on projecting but CMY
is based on ink.
RGB is used for projecting light but
CMY is used for reflecting light
RGB offers a much wider range of
colors than CMY
RGB scheme can produce colors that
are more vivid and vibrant.
