lzari压缩算法

这是一个基于LZARI算法的数据压缩的类.Haruhiko Okumura 于1989年7月4日用C语言写实现了这个算法.但是上面用到了一些全局或静态的变量,在MFC下用起来很不方便.作者把它改写成了一个C++类,使它可以方便的压缩和解压缩。(LZARI algorithm based on the type of data compression. Haruhiko SAP in 1989, July 4 C language daily wrote realization of this algorithm. But above uses some static or global variables, using the MFC which are very convenient. Authors rewrite it became a category C, it can be to facilitate the compression.)

说明：  利用gzip.dll解压http请求返回的内容。内附gzip.dll。参考网上资料自己写的VB6工程源码。自己编译EXE的时候注意把gzip.dll释放到exe所在目录。(Use gzip.dll to decompress the content returned by HTTP request. Gzip.dll is attached. Refer to the VB6 project source code written by myself.)

视音频课程作业，对视频抽帧，对单张图片进行yuv420采样、DCT变化、量化以及反量化、IDCT变化(Jpeg Encoding & Decoding)

利用Huffman编码方式对一段文字进行编码和解码。哈夫曼编码是可变字长编码(VLC)的一种。(Using the Huffman encoding method for encoding and decoding of a paragraph of text. Huffman code is a variable length coding (VLC) is a kind of.)

利用C++实现的插入,删除,增加接点等功能(The use of C++ Realized insert, delete, increase the contact and other functions)

霍夫曼编码的C++实现，含word详细叙述文档，详细注释。(Huffman coding C++ to achieve, including the word detailed description of the documents, detailed notes.)

解压ZIP格式的文件，VC++写的，完全可用的，希望你能喜欢。(Extracting ZIP format file write the VC++, completely available, hope you like it.)

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.)

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)
