用matlab实现的EZW编码解码，对图像进行小波变换，EZW算法搜索小波系数矩阵，包括熵编码（HUFFMAN）-achieved using Matlab EZW codec, the image wavelet transform, EZW wavelet algorithm search coefficient matrix, including entropy coding (HUFFMAN)

该工具包囊括了无向图模型的一些常用算法，包括随机场模型，预测算法，解码算法和采样算法，非常实用。-UGM is a set of Matlab functions implementing various tasks in probabilistic undirected graphical models of discrete data with pairwise (and unary) potentials。
