Shapiro提出的内嵌零树小波编码算法(EZW Embedded Zerotree Wavelet),其出发点在于小波变换后各级子带系数之间在空间上和方向上所呈现出带间相似性,这种空间相似性可以用一种新型的数据结构--零树(Zerotree).EZW算法就是充分利用这种相似性,获得高性能的图像编码算法.(Shapiro' s embedded zero tree wavelet coding algorithm (EZW Embedded Zerotree Wavelet), whose starting point is at all levels of sub-band wavelet transform coefficients and the direction in space with the similarity between shows, this space can be similar with a new data structure- zero tree (Zerotree). EZW algorithm is to take full advantage of this similarity, access to high-performance image coding algorithms.)
