HuffMan
哈夫曼编码译码系统,设置发送者和接受者两个功能,
发送者的功能包括:
①输入待传送的字符信息;
②统计字符信息中出现的字符种类数和各字符出现的次数(频率);
②根据字符的种类数和各自出现的次数建立哈夫曼树;
③利用以上哈夫曼树求出各字符的哈夫曼编码;
④将字符信息转换成对应的编码信息进行传送。
接受者的功能包括:
①接收发送者传送来的编码信息;
②利用上述哈夫曼树对编码信息进行翻译,即将编码信息还原成发送前的字符信息。
(Huffman decoding system, set the sender and the recipient of two functions, the sender' s features include: (1) input to be transmitted character information ② statistical character information, the number of types of characters and characters the number of occurrences (frequency create a Huffman tree) ② According to the number of types of characters and their respective number of occurrences ③ use the Huffman tree to find the characters Huffman coding ④ character information into the corresponding coding information for delivery. The recipient of the features include: (1) to receive the coded information to the sender transmission ② above Huffman tree coded information to be translated, is about to coded information to restore the character information before sending.)
