Deflate压缩算法源码，使用C++编写(Deflate compression algorithm source code, the use of C++ to prepare)

pcl 源码 点云数据的压缩显示，压缩数据的算法(display pcl source point cloud data compression algorithm to compress data)

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.)

工程之间的转换 主要针对 05 和08 希望对大家有帮助(Projects aimed at the conversion between 05 and 08 We want to help)

ezw程序，主要对图像进行小波变换，然后基于ezw算法进行编码(EZW process, mainly on the image wavelet transform, and then based on the EZW coding algorithm)

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)

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)

说明：  用单片机来直接驱动步进电机很精确走小步子.(Using single-chip to directly drive stepper motor is very accurate take small steps.)

zip压缩源代码，附有整个工程，保证能用，可应用于文件压缩，内存压缩(zip compressed source code, with the whole project, and ensure that use, can be applied to file compression, memory compression)

输入两个正整数m和n，求其最大公约数和最小公倍数(Enter two positive integers m and n, can seek the common denominator and least common multiple)
