bmp转换为jpeg,jpeg压缩的源代码 程序用vc实现了bmp图片转换成jpeg图片(converted to jpeg bmp, jpeg compression source code procedures used vc realized bmp images converted into jpeg photos)

罚函数法matlab程序.希望对大家有用.(Matlab program SUMT. Wishes to all useful.)

行程编码，JPEG压缩编码（基本系统）(itinerary encoding, JPEG compression coding (basic system))

有关算术编码对文本压缩的程序在c++环境中实现(about arithmetic compressed)

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)

说明：  支持7zip压缩解压缩功能，c语言源码。(Support 7zip compression and decompression function, C language source code)

霍夫曼编码程序 对给定的概率 生成霍夫曼编码 希望大家给点意见(Huffman encoding procedure to generate the probability of a given Huffman code to the point I hope everyone)

Jepg2000的压缩解压(Jepg2000 compression decompression)

用c语言编写的无损压缩中的熵编码的编码和解码程序！ 很实用的！(prepared by the lossless compression of the entropy coding coding and decoding process! Very practical!)

一个jpeg编码程序，有效实现了图像的jpeg压缩，是一个非常好的编码试例。(a jpeg coding procedures, the effective realization of the jpeg image compression, is a very good coding test cases.)
