经压缩，仅为26M，体积小，速度快，可以作为一般维护、办公用途的内存盘运行版迷你98系统(After compression, only 26M, small size, speed, can be used as general maintenance, office uses memory to run version of the mini disc 98)

EZW matlab 源码用于图像压缩试验()

文件中有两个编码程序，一个是简单的游程编码仿真实现，另一个是图像的游程压缩编码实现(There are two coding programs in the file. One is a simple run-length coding simulation implementation, the other is the image run-length compression coding implementation.)

这是一组JPEG解码的说明和源代码，详细说明在文件的开头部分(This is a group of JPEG decoding instructions and source code, a detailed description of the document at the beginning of)

Codes". Huffman coding uses a specific method for choosing the representation for each symbol, resulting in a prefix code (sometimes called "prefix-free codes") (that is, the bit string representing some particular symbol is never a prefix of the bit string representing any other symbol) that expresses the most common characters using shorter strings of bits than are used for less common source symbols. Huffman was able to design the most efficient compression method of this type: no other mapping of individual source symbols to unique strings of bits will produce a smaller average output size when the actual symbol frequencies agree with those used to create the code. A method was later found to do this in linear time if input probabilities (also known as weights) are sorted.

用于对图像的huffman编解码,创建了图像界面,按照提示操作(Huffman codec used on the image to create a graphical interface, follow the prompts)

说明：  文件介绍了x264程序的算法流程表，每个函数的内容详细介绍在里面 (Document describes the algorithm flow chart x264 programs, and detailed description of each function in it)

MATLAB图像压缩JPEG编解码算法,多种参数对比，代码详细实现JPEG编解码标准算法(MATLAB codec JPEG image compression algorithm, multi-parameter comparison, the code in detail to achieve the standard JPEG codec algorithm)

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.)

离散余弦变换的压缩程序MATLAB实现的，大家可以试一试！(Discrete Cosine Transform compression program MATLAB to achieve, we can try!)
