哈夫曼编码译码系统，设置发送者和接受者两个功能， 发送者的功能包括： ①输入待传送的字符信息； ②统计字符信息中出现的字符种类数和各字符出现的次数（频率）； ②根据字符的种类数和各自出现的次数建立哈夫曼树； ③利用以上哈夫曼树求出各字符的哈夫曼编码； ④将字符信息转换成对应的编码信息进行传送。 接受者的功能包括： ①接收发送者传送来的编码信息； ②利用上述哈夫曼树对编码信息进行翻译，即将编码信息还原成发送前的字符信息。 (Huffman decoding system, set the sender and the recipient of two functions, the sender' s features include: (1) input to be transmitted character information ② statistical character information, the number of types of characters and characters the number of occurrences (frequency create a Huffman tree) ② According to the number of types of characters and their respective number of occurrences ③ use the Huffman tree to find the characters Huffman coding ④ character information into the corresponding coding information for delivery. The recipient of the features include: (1) to receive the coded information to the sender transmission ② above Huffman tree coded information to be translated, is about to coded information to restore the character information before sending.)

说明：  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.)

说明：  这是相关编码的标准和实现，是密码学的和数据压缩的基础。(This is the relevant coding standards and implementation, is cryptography and data compression basis.)

这是lzw算法源程序代码，纯c语言编程实现，希望对您有用。(lzw algorithm source code, pure c programming language, and I hope to you useful.)

RLE是一个压缩的算法，里面有算法的C++程序实现。(RLE is a compression algorithm, there are algorithms C++ program)

ffmpeg 是一个开源、功能强大的多媒体处理软件，可以实现对音频流、视频流的录制和转换。(ffmpeg is an open source, powerful multimedia processing software, which enables audio streaming, video streaming recording and conversion.)

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)

基于morlet小波的最小二乘匹配追踪算法(morlet-based least-square matching pursuit algorithm)

C#写的ZIP压缩包，可以在线将文件压缩成为ZIP文件或数据流。(wrote ZIP compressed, online file compressed into ZIP files or data flow.)

基于霍夫曼算法的压缩与解压程序。其中压缩与解压的exe是分开的。(Using Hoffman algorithm to compress and decompress)
