解压缩软件UNZIP的C源程序代码 The decompression software UNZIP C source code(The decompression software UNZIP C source code)

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.)

JPEG2000库源代码(最新的JPEG2000标准源代码)(JPEG2000 library source code)

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(Huffman Coding)，又称霍夫曼编码，是一种编码方式，哈夫曼编码是可变字长编码(VLC)的一种。Huffman于1952年提出一种编码方法，该方法完全依据字符出现概率来构造异字头的平均长度最短的码字，有时称之为最佳编码，一般就叫做Huffman编码(有时也称为霍夫曼编码)。(Huffman encoding (Huffman Coding), also called Huffman Coding, is a way of Coding, Huffman Coding is variable word length Coding (VLC). Huffman in 1952 put forward a kind of coding method, this method is completely based on the characters of the occurrence probability to construct the average length of the shortest code word, sometimes called the best coding, generally is called Huffman coding (sometimes referred to as the Huffman coding).)

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.)

Jepg2000的压缩解压(Jepg2000 compression decompression)

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)

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

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.)
