I ve written some many years ago dynamic HUFFMAN algorithm to compress and decompress data. It is mainly targeted to data with some symbols occuring more often than the rest (e.g. having some data file consisted of 3 different symbols and their total number of occurence in that file s1(1000), s2(200), s3(30) so the total length of file is 1000+200+30=1230 bytes, it will be encoded assigning one bit to s1 and 2 bits to s2, s3 so the encoded length will be 1*1000+2*(200+30)=1460 bits=182 bytes). In the best case the file consisted of just one symbol will be encoded with compression ratio as 1:8. HUFFMAN coding is used in image compression, however in JPEG2000 arithmetic codec is imployed.

Library and command line program for HUFFMAN encoding and decoding both files and chunks of memory. The encoder is a 2 pass encoder. The first pass scans the data and builds the HUFFMAN tree. The second pass encodes the data. The decoder is one pa

HUFFMANEncoder 一个使用java编写的HUFFMAN编码程序,根据文本(此处使用DecOfInd.txt)中的字母和符号出现的次数进行HUFFMAN编码并且转为01字符输出,即文件DecOfInd.huf。

HUFFMANDecoder 使用java编写的HUFFMAN解码器,通过读取HUFFMANEncoder产生的DecOfInd.huf编码文件,进行解码从而恢复成可读取的原文件。配合HUFFMANEncoder使用。此处使用的是指定的text文件,可自行更改。
