是一个相当不错的啊

huffman的压缩与解压程序，其中CODE为压缩程序，DECODE为解压程序，文本为测试文件-Huffman compression and decompression procedures, which CODE procedure for compression, DECODE for decompression procedures, the text of the test document

今天看到的一个还不错的压缩算法程序，希望能对大家的编程能力提高有所帮助！-Today saw a pretty good compression algorithm program, hoping to increase our programming ability to be helpful!

用C语言实现了LZ77算法。程序独特之处在于使用了64KB大小的固定长度窗口，利用此方法可分块压缩数据。-realize LZ77 algorithm by C language.Specially program uses a 64k stable length window.It can compress data by block by using this method.

鉴于网上公布的x264调用较为复杂，使很多新手不适，我特意将其进行了简单的封装，并提供了 lib 和 测试程序，该程序已经通过编译，修改 宽高及文件路径等即可运行-In view of online publication called the x264 is more complicated, does not make a lot of novice, I made it for a simple package, and provides a lib and test procedures, the procedures have been adopted by the compiler, modify the path wide and so high and documents can be run

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

控件台应用程序。 采用哈夫曼编码对文件进行压缩解压。先将文件各字节读出，统计频率。进行哈夫曼编码，将编码重新写入文件。 编码命令：c 解码命令：d 对于编码的output file和解码的input file可以省略后缀，则默认采用.hfm。-huffman

仿WinRar解压缩VB版 这个示例就是利用这个动态链接库进行的一些操作，但目前还没有压缩文件的功能，里面的dll函数接口还需要进一步的解析和查找资料，官方好像也没有提供，希望有知道的网友也可以提供一下。更希望感兴趣的网友继续进行挖掘和开发。 源代码附有详细的注释和文档说明。使用前请把压缩包里的 UnRar.dll拷贝到你的计算机的系统文件夹下，如 WindowsSystem32下。-WinRar imitation extract VB version of this example is the use of the dynamic link library to carry out some operation, but it has not been compressed files, inside the dll interface function need further analysis and search for information, the official did not seem to offer hope to have users know that you can provide. Also hope that users are interested in continuing to carry out excavation and development. Source code with detailed notes and documentation. Please use the pre-compression of the bag UnRar.dll copy to your computer s System Folder, such as under WindowsSystem32.

此为基于二代提升小波的阈值压缩算法源码，其中可以设置小波变换的分解层数，使用的小波名称，及各层阈值设置计算公式中的参数。并将低频系数转化为十六进制，方便在其上进一步压缩，如采用Huffman压缩等，程序思路清楚，附有完整的注释，可以使用多种小波，并且很好得体现了二代小波的思想，对于初学小波者帮助很大。-based on the second generation of this upgrade wavelet compression algorithm threshold source, which can set wavelet transform decomposition level, the use of wavelet name, threshold levels and set the formula for calculating the parameters. And low-frequency coefficients into hexadecimal facilitate its further compression, such as the Huffman compression. procedures ideas clearly, with the integrity of the Notes, you can use a variety of wavelet, and reflected very well in the second generation wavelet thinking, For beginners who wavelet of great help.
