Coding used to compact data by representing the more common events with short codes and the less common events with longer codes when necessary. Note: Huffman coding is used in Group 3 Facsimile. See also code , coding , compaction , data , data compaction , encode , event , facsimile ( ...
Huffman coding Huffman coding explained Taken fromwikipedia In computer science and information theory, Huffman coding is an entropy encoding algorithm used for lossless data compression. The term refers to using a variable-length code table for encoding a source symbol (such as a character in a ...
HuffmanCoding
In Huffman coding, fixed-length blocks of the source symbols are mapped onto variable-length binary blocks. Huffman code is a prefix-free code, which can thus be decoded instantaneously and uniquely. Huffman codes are formulated to be an optimal code, i.e., they achieve the shortest average ...

Arithmetic coding can also be used to efficiently code a general probability distribution but the additional complexity of an arithmetic coder can be a drawback in some applications. SUMMARY OF THE INVENTION The present disclosure addresses the problem of developing an infinite code tailored to a...
