对数字图像进行预测编码，并用MATLAB仿真 只做了预测部分，符号编码未作-Research on Predictive Coding and its application in compress of image

对不同格式数字图像进行哈夫曼编码压缩，通过matlab软件仿真，最后得到了压缩图像，实现了本课题的基本要求。通过仿真得知哈夫曼编码为无损压缩。-Huffman coding digital image in a different format, by Matlab software emulation, finally got the compressed image, to achieve the basic requirements of this topic. Through simul
