In combination with the thoughts of former pixel predictive coding method and Lempel-Ziv-Welch (LZW) coding, in order to tackle the problem of low efficiency on signal compression of signals with high changing frequency, a sort of lossless image compression coding method was proposed. In this method, the correlation between pixels of the picture was used to construct a static dictionary, and the image could be compressed losslessly by looking and coding the data which was formerly predictive coded. The experiment results show that the proposed method is easy to realize and achieves higher compression efficiency than LZW algorithm and WinZIP algorithm.
