WebbShannon Fano Compression Algorithm. This is implementation code for shannon_fano encoding in python which is used for compressing data. It uses probability based technique to find occurrence of each character in string and then encoding the most occurrence character to represent it with less number of bits. Webb24 jan. 2024 · Shannon Fano Algorithm is an entropy encoding technique for lossless data compression of multimedia. Named after Claude Shannon and Robert Fano, it assigns a code to each symbol based on their probabilities of occurrence. It is a variable-length encoding scheme, that is, the codes assigned to the symbols will be of varying lengths.
