说明：  利用哈夫曼树对简单文件进行压缩和解压缩，对数据的压缩集成(Compression and Decompression of Simple Files Using Huffman Tree)

lzw压缩算法的C语言实现，包含压缩和解压缩的原理及实现代码(failed to translate)

JPEG压缩核心变换DCT实现源码，用matlab7.0实现(JPEG compression core transform DCT achieve source used to achieve matlab7.0)

灰色系统用于预测未知数据，是一种比较好的方法，此程序只需改变原始数据即可得到结果！(Gray system is used to predict the unknown data is a better method, this procedure simply by changing the raw data you can get the results!)

解压ZIP格式的文件，VC++写的，完全可用的，希望你能喜欢。(Extracting ZIP format file write the VC++, completely available, hope you like it.)

图片压缩代码，适用于DCT JPEG图片压缩。(Image compression code, applicable to DCT JPEG image compression.)

OMP,很好的OMP程序，应用于压缩感知中的。与以前的程序有点不同(OMP, good OMP program, applied to the compression of perception. Is a little different with previous program)

说明：  本系统运用LZ77字典算法、懒惰匹配算法和Huffman编码算法，使用Java语言在Jbuilder2006环境下设计了使用GZIP算法对文件压缩与解压缩的实现程序。用户可以根据自己的需求，使用此程序方便地对文件进行压缩或者解压缩操作。(This system uses LZ77 dictionary algorithm, lazy matching algorithm and Huffman coding algorithm, and uses Java language to design the implementation program of gzip algorithm for file compression and decompression under the environment of JBuilder 2006. Users can use this program to compress or decompress files conveniently according to their own needs.)

课设时做的学生成绩管理系统，希望对大家有参考价值(Lesson set up to do when the student achievement management system that everyone would like to have reference value)

呃，就是用赫夫曼算法写的压缩解压程序。非常粗糙，只能压缩英文文章。因为里面的字符概率是基于自然语言的，源代码之类的没法压缩。而且会抛弃最后几个字母，嘿嘿。为了交作业，没有好好写。改一下下应该能挺好的。压缩比能到60 吧(Uh, is to use Huffman compression decompression algorithm written procedures. Very rough, only compress English articles. Because there is the probability of characters based on natural language, the source code and the like can not compressed. And will abandon the last few letters, hehe. For homework, not properly written. The following should be able to change it quite good. Compression ratio to 60 of it can be)
