采用通用码书实现存储受限矢量量化

针对图像源矢量量化（VQ）过程中码书储需很大空间面空间又有限的矛盾，提出了一种采用通用码书实现存储受限矢量量化（CSVQ）的解决方案。各种图像源（矢量源）所用的子码书都可从这个通用码书中提取出来，而这些子码书之间存在交集，大大节约了所需存储空间，并且，各种矢量源可以以不同的速率编码。

Implementation of constrained-storage vector quantization with universal codebook

This article proposes a new scheme based on a size limited universal codebook to solve the contradiction between the performance of VQ system and the requirement of enormous memory space. This framework allows each source codebook to consist of any desired subset of the universal codevectors and provides greater design flexibility which improves the storage-constrained performance.
