Lossy compression — A lossy compression method is one where compressing data and then decompressing it retrieves data that may well be different from the original, but is close enough to be useful in some way. Lossy compression is most commonly used to compress… … Wikipedia
Distributed source coding — (DSC) is an important problem in information theory and communication. DSC problems regard the compression of multiple correlated information sources that do not communicate with each other.[1] By modeling the correlation between multiple sources … Wikipedia
Shape coding — is a method of design of a control that allows the control s function to be signified by the shape of the control. It was used successfully by Alphonse Chapanis on airplane controls to improve aviation safety.External links*… … Wikipedia

Block Truncation Coding — Block Truncation Coding, or BTC, is a type of lossy image compression technique for greyscale images. It divides the original images into blocks and then uses a quantiser to reduce the number of grey levels in each block whilst maintaining the… … Wikipedia
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
Shannon's source coding theorem — In information theory, Shannon s source coding theorem (or noiseless coding theorem) establishes the limits to possible data compression, and the operational meaning of the Shannon entropy.The source coding theorem shows that (in the limit, as… … Wikipedia
Multiple description coding — (MDC) is a coding technique that fragments a single media stream into n substreams (n ≥ 2) referred to as descriptions. The packets of each description are routed over multiple, (partially) disjoint paths. In order to decode the media… … 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
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
Transform coding — is a type of data compression for natural data like audio signals or photographic images. The transformation is typically lossy, resulting in a lower quality copy of the original input.In transform coding, knowledge of the application is used to… … Wikipedia
