利用霍夫曼编码算法对数字图像进行压缩及解压缩处理，解压出来的图像与源图像几乎完全一致，峰值信噪比为无穷大,The use of Huffman coding algorithm for digital image compression and decompression processing, extracting images from the source image is almost exactly the same infinite PSNR

huffman编码用于图像的压缩和解压，很好用的，可以用于各类图像的处理-huffman coding for image compression and decompression, useful, and can be used for all kinds of image processing
