Shannon-fano-elias 符号
WebbShannon Fano Algorithm is an entropy coding technique used for lossless data compression. It uses the probabilities of occurrence of a character and assigns a unique variable-length code to each of them. If c is a character, Probability (c) = Frequency (c) / sum of frequencies Understanding the algorithm Webb20 nov. 2024 · 算法. Shannon-Fano算法其实是最早的变长无损压缩编码算法，比 Huffman算法 早一点点，其压缩效率比Huffman稍差一点点，因此没有后者有名。. …
