Many images display devices allow only a limited number of colors to be simultaneously displayed. Usually, this set of available colors, called a color map, may be selected by a user from a wide variety of available colors. This color quantization problem is considered in two parts : the selection of an optimal color map and optimal mapping of each pixel of the image to a color from color map.
After convert RGB color images to YUV color images, this paper presents an analysis of quantization process of color images using suggested method of color map generation by histogram. The result compared JPEG and proposed method.
