Lossless data compression — is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. The term lossless is in contrast to lossy data compression, which only allows an approximation of the original data to be… … Wikipedia
Dynamic Markov compression — (DMC) is a lossless data compression algorithm developed by Gordon Cormack and Nigel Horspool [1]. It uses predictive arithmetic coding similar to prediction by partial matching (PPM), except that the input is predicted one bit at a time (rather… … Wikipedia
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
Quality factor (video compression) — The quality factor (qf) of encoded video streams (a.k.a. frame quality) is the amount of bits for each pixel in a given video. Calculation The quality factor can be calculated by the formula:Q f = frac{1000 cdot b}{v cdot h cdot f}where Q f is… … Wikipedia
