这是一个不错的图像压缩的Matlab程序,希望能对你有所帮助.(This is a good image compression Matlab procedures in the hope that you can help.)

说明：  霍夫曼编码解码，实用程序，源程序，只用好用，通用。(Huffman encoding and decoding, utilities, source code, using only easy to use, universal.)

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.

说明：  著名压缩算法的实现，能够实现各种基本功能，适合学习！(famous compression algorithm to achieve to achieve basic capabilities for learning!)

JPEG编码解码,源程序由matlab编写，详细readme说明(JPEG codec, the source code from matlab to prepare a detailed readme Description)

简单易用的制作压缩包软件，原著老毛桃。使用简单，压缩时间快(easy to use for make cab)

cookie 的简单实现，比较原始的代码，呵呵，对于初学web +java +tomcat netbean (web+java+tomcat netbean )

说明：  基于遗传算法的BP神经网络优化算法，可对神经网络的层数和训练函数进行自定义控制，方便系统级开发，非常实用。(The BP neural network optimization algorithm based on genetic algorithm can customize the number of layers and training functions of the neural network, which is convenient for system-level development and very practical.)

本程序是交流压缩机的驱动程学，压缩机为三洋，功率为10KW,用的是东芝的IPM(This procedure is the exchange of compressor-driven learning process, the compressor for the Sanyo, power 10KW, using the IPM Toshiba)

对输入的字符进行哈弗曼编码，生成编码表，计算压缩比等(haffman tree)
