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 .

WebHuffman coding is a greedy algorithm, reducing the average access time of codes as much as possible. It is a tree-based encoding technique. This method generates variable-length bit sequences called codes in such a way that the most frequently occurring character has the shortest code length. WebHuffman tree generated from the exact frequencies of the text "this is an example of a huffman tree". The frequencies and codes of each character are below. Encoding the sentence with this code requires 135 (or 147) bits, as opposed to 288 (or 180) bits if 36 characters of 8 (or 5) bits were used.
