Huffman vs arithmetic coding

Web哈夫曼编码其实思想就是:对于更高频的符号,使用更短的编码。 这样在对整个信息进行编码时,就可以进行大幅度压缩。 比如一段英文字符:AABABCABAB,A 出现了 5 次,B 出现了 4 次,C 出现了 1 次。 如果我们用定长编码来进行信息编码,那么每个符号至少需要 2 个 bit 来表示: A:01,B:10,C:11。 整首诗的编码长度为:5*2 + 4*2 + 1*2 = 20 bit。 … http://www.yearbook2024.psg.fr/WGuf1_adaptive-huffman-coding-matlab-code.pdf
