Description: 来有人提出了一种动态的哈夫曼编码方法。动态哈夫曼编码使用一棵动态变化的哈夫曼树，对第t+1个字符的编码是根据原始数据中前t个字符得到的哈夫曼树来进行的，编码和解码使用相同的初始哈夫曼树，每处理完一个字符，编码和解码使用相同的方法修改哈夫曼树，所以-was raised to a dynamic Huffman coding method. Dynamic Huffman coding using a dynamic changes in the Huffman tree for the first t a character encoding is based on the original data before t characters in the Huffman tree for the encoding and decoding using the same initial Huffman tree, each dealing with a character encoding and decoding using the same side Law Revision Huffman tree.

Description: 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.
