Adaptive Transform Acoustic Coding — (ATRAC) est une technique de compression audio avec pertes développée par Sony en 1992 et utilisée notamment dans les appareils MiniDisc. Seul le ATRAC Advanced Lossless propose une compression sans pertes. Aujourd hui, le format ATRAC est… … Wikipédia en Français
Image compression — is the application of Data compression on digital images. In effect, the objective is to reduce redundancy of the image data in order to be able to store or transmit data in an efficient form.Image compression can be lossy or lossless. Lossless… … 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
Fractal transform — The fractal transform is a technique invented by Michael Barnsley et al. to perform lossy image compression.This first practical fractal compression system for digital images resembles a vector quantization system using the image itself as the… … Wikipedia
Advanced Video Coding — H.264/MPEG 4 AVC ist ein Standard zur hocheffizienten Videokompression. Er wurde zunächst von der ITU (Study Group 16, Video Coding Experts Group) unter dem Namen H.26L entwickelt. Im Jahre 2001 schloss sich die ITU Gruppe mit MPEG Visual… … Deutsch Wikipedia
Modified discrete cosine transform — The modified discrete cosine transform (MDCT) is a Fourier related transform based on the type IV discrete cosine transform (DCT IV), with the additional property of being lapped: it is designed to be performed on consecutive blocks of a larger… … Wikipedia

Discrete cosine transform — A discrete cosine transform (DCT) expresses a sequence of finitely many data points in terms of a sum of cosine functions oscillating at different frequencies. DCTs are important to numerous applications in science and engineering, from lossy… … Wikipedia
Discrete wavelet transform — An example of the 2D discrete wavelet transform that is used in JPEG2000. The original image is high pass filtered, yielding the three large images, each describing local changes in brightness (details) in the original image. It is then low pass… … Wikipedia
Wavelet transform — An example of the 2D discrete wavelet transform that is used in JPEG2000. In mathematics, a wavelet series is a representation of a square integrable (real or complex valued) function by a certain orthonormal series generated by a wavelet … Wikipedia
