基于Lossy-to-Lossless Image Compression Based on Reversible Integer TDLT/KLT的压缩算法的matlab实现，在增加ROI编码模块，算法详细可以查看论文《Lossy-to-lossless image compression based on multiplier-less reversible integer time domain lapped transform》。程序由main.m函数开始运行，输入参数有3个，分

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
