Proved, LP algorithm does not compare the similarity between all clusters, and the implementation of speed, a large number of documents for a collection are more practical.
实验证明，LP算法不需要比较所有簇之间的相似度，执行速度较快，适合大量文件的集合，实用性更高。
SPIHT is a well recognized coding algorithm due to its high effecient performance. But SPIHT is unsuitable for high-speed hardware implementation. An improved coding algorithm to SPIHT is introduced.
基于小波变换的SPIHT图像压缩方案是一种实用高性能图象压缩编码算法，但原始SPIHT算法链表式编码限制了其在高速处理中的应用。
