摘要
如何对一幅彩色图像的颜色进行量化优化处理，选用有限种类有代表性的颜色，效果相对较佳地再现该图像是彩色图像处理中的重要问题．在分析比较了现有几种方法的基础上，提出了一种新算法“变球法”．实践表明，该法可获得高的显示质量并具有高的运行效率．
It is important in color image processing to optimize the color quatization for a given color picture and achieve relatively better quality while representing it with this quantization. Based on analysing and comparing the previous algorithms, this paper deals with a new algorithm-“variable ball method”. The result of implementation indicates that the new algorithm has better image quality and is more efficient.
