EZW算法的过程详解和Matlab代码（1）构建扫描次序表（修正小波树结构）写出EZW算法的Matlab程序，可以实现图像的任意级别的小波分解和重构、以及任意精度的EZW编解码过程。下面，我们以一幅16*16的Lena局部图像经过3级小波分解后的小波数据为例详细的说明EZW算法的编解码过程，并给出相应的Matlab代码。-Explain the process of EZW algorithm and Matlab code (1) building a scan list (Amendment wavelet tree structure) to write the Matlab program EZW algorithm, can achieve any level of image wavelet decomposition and reconstruction, as well as the accuracy of any EZW codec process. Next, we 16* 16 in a partial image of Lena after three after the wavelet decomposition as an example of the wavelet detail data EZW codec algorithm process and the corresponding Matlab code is given.
