摘要
颜色量化是真实图形显示的一个重要环节。它的主要任务是将一幅有Ｎ个象素点的真实图用不超过Ｋ（Ｋ＜＜Ｎ）种颜色近似表示，以使这幅图能在颜色表长为Ｋ的显示设备上输出。本文提出了一种基于编码的颜色量化算法，此算法速度快，所生成的图形效果较好。
Color quantization is an important problem in rendering. The main task ofcolor quantization is to approximate an image of N pixels with no more than K(K<<N)colors so that the image could be output on a display device with a color palette of onlyK items. A quantization algorithm in terms of color encoding is described in this paper.The algorithm is proven to be effective.
