WebDec 12, 2014 · In Shannon-Fano coding you need the following steps: A Shannon–Fano tree is built according to a specification designed to define an effective code table. The … In the field of data compression, Shannon–Fano coding, named after Claude Shannon and Robert Fano, is a name given to two different but related techniques for constructing a prefix code based on a set of symbols and their probabilities (estimated or measured). Shannon's method … See more Regarding the confusion in the two different codes being referred to by the same name, Krajči et al write: Around 1948, both Claude E. Shannon (1948) and Robert M. Fano (1949) independently … See more Shannon's algorithm Shannon's method starts by deciding on the lengths of all the codewords, then picks a prefix code with those word lengths. Given a source with probabilities Once the codeword … See more Outline of Fano's code In Fano's method, the symbols are arranged in order from most probable to least probable, and … See more Neither Shannon–Fano algorithm is guaranteed to generate an optimal code. For this reason, Shannon–Fano codes are almost never used; Huffman coding is almost as … See more
