采用小波零树的EZW压缩编码算法，matlab实现代码

霍夫曼压缩解压缩算法-Huffman compression decompression algorithms

把链表S中从第m个元素起共n个元素存储到s中，成功返回1，否则返回0int LEN(STRING S) -S in the list from the first m elements from a total of n elements stored in the s successful one back, otherwise return 0int LEN (STRING S)

图象压缩算法的实现,十分具有参考价值的,赫赫有名-Image compression algorithm is very valuable and well-known

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.

介绍嵌入式的视频,来自上海交通大学,这是一个播放器的解压缩的程序-introduced Embedded Video from Shanghai Jiaotong University, which is a player in the process extract

好的压缩工具，主要对MP3再压缩，给大家分享-good compression tools, mainly for MP3 compression again, to share

递归下降识别程序-recursive declined identification procedures

关于JPEG压缩和置乱的 很不错的 很实用-on JPEG compression and scrambling of the very good very practical

这是一组JPEG解码指令和源代码，详细描述了文档开头部分

lz编码译码LZW就是通过建立一个字符串表,用较短的代码来表示较长的字符串来实现压缩. -lz codec LZW is through the establishment of a string table, with a shorter code to represent a long string to achieve compression.
