An Improved LZW Compression Algorithm
Junwei Ji · Jisuanji gongcheng · 2005
In lossless compression area, dictionary compression method has been regarded as a kind of better method. It has higher compressionratio and is accomplished quickly, however it couldn’t dispose of the relation between global and local adaptability. An improved LZW algorithm ispresented, which has better global and local adaptability as well as the advantage of dynamic and static dictionary. The computer simulationsdemonstrate that the algorithm is a simple better-improved algorithm, has higher compression ratio, algorithm stabilization and could meet the users’different demands.
