huffman編碼. 把一個(gè)英文字母,空格,句號(hào).一共有28個(gè) character. 先求每個(gè)字符出現(xiàn)的頻率. 然后用頻率對(duì)這個(gè)文件進(jìn)行哈夫曼編碼. 然后再進(jìn)行解碼. 運(yùn)行的時(shí)候需要在VC++ 工程->設(shè)置->調(diào)試->程序變量里加E:\sample.txt E:\ENCODE.txt E:\decode.txt 然后把英文文件放到E盤(pán)里.名叫samole.txt, 還有在E里新件2個(gè)txt文件.名叫ENCODE.txt,decode.txt. 編碼后的二進(jìn)制save到ENCODE.txt,解碼后的英文字符save到decode.txt了.

1、簡(jiǎn)介 此代碼是IS0 13818-5 MPEG2系統(tǒng)層協(xié)議分析代碼，經(jīng)過(guò)我的一點(diǎn)修改，現(xiàn)在終于可以在VC++ 6.0下編譯運(yùn)行, 發(fā)布上來(lái)獻(xiàn)給那些為了理解MPEG2系統(tǒng)層協(xié)議而苦苦加班的程序員。為了可以在windows下編譯，我修改了部分操作系統(tǒng)相關(guān)代碼，注解掉了一些main函數(shù)，只留下decode.cpp中的main函數(shù)沒(méi)有注解，所以編譯后的程序是TS流系統(tǒng)層解碼分析程序，如果要實(shí)現(xiàn)其他功能如ENCODE，只要把decode.cpp中的main函數(shù)注解，把ENCODE.cpp中的main函數(shù)注解去掉即可。

XTHIDE is a GUI that allows the user to hide a text message in an image file. The user will be asked for a key that will be used to both ENCODE and decode the text into an image. The key can be of length from 2 to 900 characters. The encryption pattern for a key hell is not a subset of the encryption pattern for hello . See help. Created with version 7.01.

Huffman codes 1.In telecommunication, how do we represent a set of messages, each with an access frequency, by a sequence of 0 s and 1 s? 2.To minimize the transmission and decoding costs, we may use short strings to represent more frequently used messages. 3.This problem can be solved by using an extended binary tree which is used in the 2-way merging problem. the sourse code is to ENCODE and decode the Huffman.
