霍夫曼科丁：科丁基于OPN的Huffman编码方法

压缩用的-Compression used

一个很简单的哈夫曼编码程序!!要的就下哟!-a very simple Huffman coding process! ! To the next yo!

利用matlab编程环境，采用算术编码的方式实现字符串的无损压缩-The use of matlab programming environment, using arithmetic coding means to achieve a string of lossless compression

霍夫曼压缩算法，针对图像压缩，绝对好用，不信试试。-Huffman compression algorithm for image compression, the absolute ease of use, not to try.

In each step the LZSS algorithm sends either a character or a pair. Among these, perhaps character "e" appears more frequently than "x", and a pair of length 3 might be commoner than one of length 18, say. Thus, if we encode the more frequent in fewer bits and the less frequent in more bits, the total length of the encoded text will be diminished. This consideration suggests that we use Huffman or arithmetic coding, preferably of adaptive kind, along with LZSS.-In each step the LZSS algorithm sends either a character or a lt;position, lengthgt; pair.

本程序分两部分，分别为界面和驱动程序，其中驱动程序为压缩解压缩的核心程序。 开发环境为VC6.0。 界面部分可由crs->ddu->ddu.dsp建立工作组，编译生成的可执行程序为debug中的ddu.exe 驱动部分由crs->驱动->驱动.c编译生成可执行文件。 具体压缩解压缩操作可见《操作手册》。-This procedure was divided into two parts, namely, interface and driver, one of the drivers for the compression of the core decompression procedure. Development environment for VC6.0. Interface may be part of crs->ddu-> ddu.dsp Working Group set up, the compiler generates the executable program to debug the ddu.exe driven in part by crs-> Driver-> Driver. C compiler to generate executable file. Extract specific compression operation can be seen " manual."

通信中的压缩、解压缩。利用相对编码的原理，进行前后相减。（编程背景为温室温度测量，限定在正负50以内）。已经编译通过。-Communication compression, decompression. The principle use of the relative encoding, carried out before and after the subtraction. (Programming background greenhouse temperature measurement, limited to within plus or minus 50). Has been compiled through.

用C++实现的学生信息管理系统，实现了学生和老师的创建，添加，删除和查找，统计，界面设置飞入界面，更加人性化-With C++ Realize student information management system, students and teachers to create, add, delete, and search, statistics, interface set to fly into the interface more user-friendly

这是一个压缩和解压的程序。里面有两个工程，分别由压缩和解压的过程-This is a compression and decompression procedures. There are two works by the process of compression and decompression
