基于LZW算法的改进算法

Improved Method Based on the LZW Method

在分析LZW算法的基础上对LZW算法的缺陷进行了探讨,并对LZW算法进行了改进,大幅度减少了编码的长度,降低了匹配长度取值变化的影响,完全兼容LZW算法,在平均压缩率方面有较大的提高,而且对改进的算法进行了分析论证.

Based on the analysis of the LZW method,the deficiencies of LZW method are discussed.It has improved the method,substantially reduce the length of the code and the effects of the dereferencing changes about the matching length,embraced the LZW method completely and increased the average rate.Further,the improved method is analyzed.
