Color Quantization . The objective of color quantization is displaying a full color image (24 bits per pixel) with a restricted set of color numbers (256, 64, 16) without a significant (almost preceptually not noticeable by the spectator) lack of color impression approximation as. These four color control methods:

Color quantization digital color images can be represented using the rgb color model. You can also use floor, which is more suitable in some cases. These four color control methods:

Here is an example of each of these four methods. Normally, the intent is to preserve the color appearance of the image as much as possible, while reducing the number of colors, whether for memory limitations or compression. There are four basic methods for the selection colors. Thus, full color digital display systems use 24 bits to specify the color of each pixel on the screen.

We call the smallest possible vbox the “quantum volume.” typically, when using a colormap of 256 colors or less, 5 bits are sufficent for each component, so there are 2 15 of these quantum volumes filling the entire color space.

If colors are represented by the cielab space, the axes of lightness l* and chromaticities a* and b* have to be suitably quantized. If we specify that we only want to show the picture in 4 colors, the quantization will try. Obviously, all compressions come with a cost. Last, but not least, we need to determine appropriate similarity/distance measures for.
