实现图像的huffman编码，并得到生成矩阵和字典-Huffman realize image coding, and get a generator matrix and dictionaries

KSVD字典训练程序，用于生成适应于图像内容的稀疏字典。稀疏描述必读程序。-KSVD dictionary training program used to generate a sparse dictionary adapted to image content. Sparse descr iption of the Privacy Policy program.

利用稀疏表示进行图像去噪时，需要生成两种学习字典，该源码比较了生成的两种字典的优劣-Denoising sparse representation, it is necessary to generate two learning dictionary, which compares the generated source code of the merits of two dictionary
