JPEG里MQ算术编码测试程序 编解码器 C(MQ arithmetic coding in JPEG test procedure codec C)

说明：  一个简单的32位位图压缩算法，基本思想是，扫描像素点，后面有雷同的就记下重复次数。(A simple 32-bit bitmap compression algorithm, the basic idea is to scan pixel, behind identical repetitions on the record.)

基于哈弗曼树的压缩软件，可压缩文字和位图。(Huffman tree based compression software, compressible text and bitmaps.)

Jepg2000的压缩解压(Jepg2000 compression decompression)

哈夫曼编码，基于MFC开发。哈夫曼编码为熵编码中的最佳方法之一，广泛用于各种数据压缩技术中。-Huffman coding, based on the MFC. Huffman coding for entropy coding one of the best ways, for a wide variety of data compression technology.

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)

lzw压缩解压算法源码(The soruce of LZW compression algorithm)

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)

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.)

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)
