The mathematical representation of a color. a) Regardless of the color space used, RGB, YIQ, YUV, a color will appear the same on the screen. What is different is how the color is represented in the color space.
In the HLS color space, colors are represented based on a three-dimensional polar coordinate system where as in the RGB color space, colors are represented by a Cartesian coordinate system. b) Many ways have been devised to organize all of a system’s possible colors. Many of these methods have two things in common: a color is specified in terms of three numbers, and by using the numbers as axes in a 3D space of some sort, a color solid can be defined to represent the system. Two spaces are popular for computer graphics: RGB and HSV.

An 8-row by 8-column matrix of pels, or 64 DCT coefficients (source, quantized or dequantized). A block is the entity on which the DCT operates. Please note, that the term “block” is used for both the actual picture information, and the corresponding DCT coefficients. A block represents luminance or chrominance information.
