Huffman coding — Huffman 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 bits, as opposed of 288 bits if 36… … Wikipedia
Huffman coding — In data compression, a method of encoding data on the basis of the relative frequency of the individual elements. Huffman coding is often used with text files; the coding is based on how frequently each letter occurs, because it is a lossless… … Dictionary of networking
Adaptive Huffman coding — (also called Dynamic Huffman coding) is an adaptive coding technique based on Huffman coding. It permits building the code as the symbols are being transmitted, having no initial knowledge of source distribution, that allows one pass encoding and … Wikipedia
Modified Huffman coding — is used in fax machines to encode black on white images (bitmaps). It combines the variable length codes of Huffman coding with the coding of repetitive data in run length encoding. External links Modified Huffman coding from UNESCO . Archived… … Wikipedia
Huffman — is an American surname likely derived from the German surnames Hoffmann and Hofmann, which in English are also spelled Hoffman and Hofman. People Booker Huffman (born 1965), American professional wrestler better known as Booker T Cady Huffman… … Wikipedia
Arithmetic coding — is a method for lossless data compression. Normally, a string of characters such as the words hello there is represented using a fixed number of bits per character, as in the ASCII code. Like Huffman coding, arithmetic coding is a form of… … Wikipedia
Shannon–Fano coding — In the field of data compression, Shannon Fano coding is a suboptimal technique for constructing a prefix code based on a set of symbols and their probabilities (estimated or measured). The technique was proposed prior to the optimal technique of … Wikipedia

Codage de Huffman — Le codage de Huffman est un algorithme de compression de données sans perte élaboré par David Albert Huffman, lors de sa thèse de doctorat au MIT. L algorithme a été publié en 1952 dans l article A Method for the Construction of Minimum… … Wikipédia en Français
Canonical Huffman code — A canonical Huffman code is a particular type of Huffman code which has the property that it can be very compactly described.Data compressors generally work in one of two ways. Either the decompressor can infer what codebook the compressor has… … Wikipedia
Unary coding — is an entropy encoding that represents a natural number, n , with n − 1 ones followed by a zero. For example 5 is represented as 11110. Some representations use n − 1 zeros followed by a one. The ones and zeros are interchangeable without loss of … Wikipedia
