摘要 在充分分析嵌入式零树编码 (EZW)原理的基础上 ,提出了一种利用固定码长的游程编码对EZW的输出码流进行优化 ,降低了输出码流中连续零树根的相关性 ,达到进一步压缩数据的目的 .实验结果表明 。 On the basis of analysing the theory of embedded zerotrees coding, fixed length run-length coding is presented to optimize the output code of EZW, reducing the correlation among zerotree roots for the purpose of further data compression. The experiment result shows that this method is better than the original EZW algorithm.
