![]() The output from Huffman's algorithm can be viewed as a variable-length code table for encoding a source symbol (such as a character in a file). student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-Redundancy Codes". The process of finding or using such a code proceeds by means of Huffman coding, an algorithm developed by David A. In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression. (This assumes that the code tree structure is known to the decoder and thus does not need to be counted as part of the transmitted information.) Char 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. The frequencies and codes of each character are below. ![]() Huffman tree generated from the exact frequencies of the text "this is an example of a huffman tree". ![]()
