Webb21 dec. 2024 · Shannon Fano Coding is also an encoding algorithm used to generate a uniquely decodable code. It was developed by Claude Shannon and Robert Fano in 1949, earlier than the Huffman Coding technique. Similar to the Huffman coding, the Shannon Fano Coding also uses the probabilities of the data for encoding. Webb18 aug. 2024 · In Shannon-Fano, the population list is sorted by pop count and then repeatedly (recursively) split in two - with half the population in each half, or as close as one can get - until only two entries are left in a sub-section. Huffman has been proven to always produce the (an) optimal prefix encoding whereas Shannon-Fano is (can be) slightly ...
