Color video images have become a very important media in communication. This has increased the necessity of displaying and handling color video images on various types of computers. In computerized color image processing, most color images are represented by 24 bits per pixel. Such images usually contain a lot of redundancy and require a large amount of space to be stored. Furthermore, they require expensive full color display devices, so that many general-purpose computers which have only colormap display devices are not capable of displaying them. In order to lower the display and the storage cost, color image quantization algorithms are needed to reduce the number of colors in original images. The authors propose a color quantization method for video images which efficiently generates color quantized video images with stable color allocations
