摘要

本文介绍了两种VQ算法:(1)基于快速聚类算法(VQ- fca)的VQ算法,该算法可实现码本的生成;(2)基于部分重排序码本的VQ算法(VQ- prcb),该算法可提取相邻VQ指标之间的相关性。基于这些算法,提出了两种方案:(1)二维VQ方案和(2)三维VQ组合方案。实验结果与其他算法进行了比较,证明了该算法的优越性。

Color image compression using combined VQ algorithms
In this paper, two VQ algorithms are introduced: (1) VQ with a fast clustering algorithm (VQ-FCA) that can be implemented for codebook production, and (2) VQ with a partially reordered codebook (VQ-PRCB), that extracts the correlation between adjacent VQ indices. Based on these algorithms, two schemes are proposed: (1) 2D VQ, and (2) combined 3D VQ schemes. Experimental results are compared with other algorithms to show its advantages.
