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
Range encoding — is a data compression method defined by G N N Martin in his 1979 paper on Range encoding: an algorithm for removing redundancy from a digitized message [http://www.compressconsult.com/rangecoder/#download Range Encoder ] ] . Range encoding is… … Wikipedia
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
Entropy encoding — In information theory an entropy encoding is a lossless data compression scheme that is independent of the specific characteristics of the medium. One of the main types of entropy coding creates and assigns a unique prefix free code to each… … Wikipedia
Delta encoding — Not to be confused with Elias delta coding. Delta encoding is a way of storing or transmitting data in the form of differences between sequential data rather than complete files; more generally this is known as data differencing. Delta encoding… … 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
Run-length encoding — (RLE) is a very simple form of data compression in which runs of data (that is, sequences in which the same data value occurs in many consecutive data elements) are stored as a single data value and count, rather than as the original run. This is … Wikipedia
Byte pair encoding — or digram coding[1] is a simple form of data compression in which the most common pair of consecutive bytes of data is replaced with a byte that does not occur within that data. A table of the replacements is required to rebuild the original data … Wikipedia
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
Run-length encoding — Le run length encoding, appelé en français le codage par plages, est un algorithme de compression de données en informatique. Le système s applique essentiellement à des documents scannés en noir et blanc : au lieu de coder un bit par point … Wikipédia en Français
