transform coding
51Principal component analysis — PCA of a multivariate Gaussian distribution centered at (1,3) with a standard deviation of 3 in roughly the (0.878, 0.478) direction and of 1 in the orthogonal direction. The vectors shown are the eigenvectors of the covariance matrix scaled by… …

54Transformada de coseno discreta modificada — Para otros usos de este término, véase Transformación (desambiguación). La Transformada Discreta del Coseno Modificada, también conocida por Transformación de Coseno Discreto Modificado y por sus siglas en inglés, MDCT (Modified Discrete Cosine… …
55Color Cell Compression — is an early lossy image compression algorithm first described by Campbell et. al. in 1986.[1] It is a variant of Block Truncation Coding.[2] The encoding process works on small blocks of pixels. For each block, it first partitions the pixels in… …
56Comparison of audio formats — The following tables compare general and technical information for a variety of audio formats and audio compression formats. For listening tests comparing the perceived audio quality of audio formats and codecs, see the article Codec listening… …
57G.719 — is an ITU T standard audio codec providing high quality, moderate bit rate (32 to 128 kbit/s) wideband (20 Hz 20 kHz audio bandwidth, 48 ksps) audio coding at low computational load. It was produced through a collaboration between Polycom and… …
58Empirical orthogonal functions — In statistics and signal processing, the method of empirical orthogonal function (EOF) analysis is a decomposition of a signal or data set in terms of orthogonal basis functions which are determined from the data. It is the same as performing a… …
59Spectral flatness — is a measure used in digital signal processing to characterise an audio spectrum. A high spectral flatness indicates that the spectrum has a similar amount of power in all spectral bands this would sound similar to white noise, and the graph of… …
60Transformationskodierung — (englisch transform coding) ist eine Methode der Datenkompression für Signale wie zum Beispiel Audiosignale (1D) oder Bilder (2D). Dabei geht der eigentlichen Datenkompression meist eine Frequenz Transformation voraus. Dies hat den Vorteil, dass… …
