WebbShannon-Fano Algorithm: o Sort symbols according to the frequency of occurrences. o Recursively divide symbols into two parts, each with approximately same counts, until all … 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 chooses a prefix code where a source symbol is given the codeword length . One common way of choosing the codewords uses the binary expansion of the cumulative prob…
