Unformatted text preview: lecture note (RGBadd.gif, and CMYsub.gif) Cyan = White Red, Magenta = White Green, Yellow = White - Blue 5. The conversion between RGB and YCbCr coordinate is shown below. a) Determine the YCbCr coordinate for a color that is specified in (R,G,B) coordinate with R=100,G=200, B=50. b) Determine the (R,G,B) coordinate for a color specified in the YCbCr coordinate with Y=100,Cb=50,Cr=30. 6. Suppose you are given a 24 bit color image, with color components red, green, blue each represented by 8 bits per pixel. Now, we would like to reduce it to an 8 bit image by uniformly quantizing the red and green components to 3 bits each, and the blue component to 2 bits. Illustrate the quantizer that you would use for different components. Suppose a pixel has a color value of (R,G,B)=(200, 150, 40). What is the color after quantization? ,...
