常用色彩量化算法的性能分析

CHARACTERS ANALYSIS OF CURRENT ALOGORITHMS FOR COLOR QUANTIZATION

本文在讨论了几种常用的色彩量化算法思想的基础上，重点分析了我们在文献１中给出的一种基于八叉树的色彩量化方法的算法性能，并对这几种方法给以分析比较。说明这种八叉树算法产生的图象质量优，具有速度较快和压缩存储的效果，是一种性能好的色彩量化方法。

On the basis of discussing several current algorithms for color quantization, we analysis deeply the algorithm based on octree structure that has been presented in reference 1. At the same time of analysing and comparing the several methods mentioned in this paper, we draw the conclusion that the algorithm based on octree structure has the advantages of producing higher quality picture ,high speed and less memory .So , it's a better algorithm for color quantization.
