一个不错的自制解压缩程序-a good homemade decompression procedures

各种数据压缩和解压的源码，用mfc实现。包括熵编码，预测编码，变换编码，字典编码-A variety of data compression and decompression of the source, using mfc achieve. Including entropy coding, predictive coding, transform coding, dictionary coding

自适应的霍夫曼编码是一种扩展的熵编码方法，取得了更高的编码效果。这是几种自适应霍夫曼编码的实现方法。希望对大家有用。-adaptive huffman coding is an extended coding method ,which can get more efficient compression ratio. this is kinds of adaptive huffman coding methods. i hope it will be useful for people who research huffman code.

方便处理JPEG格式图片的基于VC的源代码-facilitate the processing of JPEG images based on the source code VC

本程序分两部分，分别为界面和驱动程序，其中驱动程序为压缩解压缩的核心程序。 开发环境为VC6.0。 界面部分可由crs->ddu->ddu.dsp建立工作组，编译生成的可执行程序为debug中的ddu.exe 驱动部分由crs->驱动->驱动.c编译生成可执行文件。 具体压缩解压缩操作可见《操作手册》。-This procedure was divided into two parts, namely, interface and driver, one of the drivers for the compression of the core decompression procedure. Development environment for VC6.0. Interface may be part of crs->ddu-> ddu.dsp Working Group set up, the compiler generates the executable program to debug the ddu.exe driven in part by crs-> Driver-> Driver. C compiler to generate executable file. Extract specific compression operation can be seen " manual."
