Filtering problem (stochastic processes) — In the theory of stochastic processes, the filtering problem is a mathematical model for a number of filtering problems in signal processing and the like. The general idea is to form some kind of best estimate for the true value of some system,… … Wikipedia
Linear predictive coding — (LPC) is a tool used mostly in audio signal processing and speech processing for representing the spectral envelope of a digital signal of speech in compressed form, using the information of a linear predictive model. It is one of the most… … Wikipedia
Bilinear filtering — is a texture filtering method used to smooth textures when displayed larger or smaller than they actually are.Most of the time, when drawing a textured shape on the screen, the texture is not displayed exactly as it is stored, without any… … Wikipedia
Collaborative filtering — (CF) is the process of filtering for information or patterns using techniques involving collaboration among multiple agents, viewpoints, data sources, etc. Applications of collaborative filtering typically involve very large data sets.… … Wikipedia
Trilinear filtering — is an extension of the bilinear texture filtering method, which also performs linear interpolation between mipmaps.Bilinear filtering has several weaknesses that make it an unattractive choice in many cases: using it on a full detail texture when … Wikipedia
Homomorphic filtering — is a generalized technique for signal and image processing, involving a nonlinear mapping to a different domain in which linear filter techniques are applied, followed by mapping back to the original domain. This concept was developed in the… … Wikipedia
Rasta filtering — and Mean Subtraction was originally introduced in connection with the Perceptual Linear Prediction(PLP) type of preprocessing; i.e. bandpass filtering in the log spectral domain. Slow channel variations should thus in principle be removed. This… … Wikipedia
Focus recovery based on the linear canonical transform — Focus recovery from defocused image is an ill posed problem since it loses the component of high freqency. Most of the methods for focus revocery are based on depth estimation theory [Most of depth recovery methods are simply based on camera… … Wikipedia
Bilineares Filtering — Die Bilineare Filterung oder bilineare Interpolation ist eine Erweiterung der linearen Interpolation, um Zwischenwerte innerhalb eines zweidimensionalen, regulären Rasters zu bestimmen. Sie wird häufig als Grafikfilter zur Skalierung von… … Deutsch Wikipedia
Algebraic code excited linear prediction — (ACELP) is a speech encoding algorithm where a limited set of pulses is distributed as excitation to linear prediction filter.The ACELP method is widely employed in current speech coding standards such as AMR, EFR, AMR WB and ITU T G series… … Wikipedia
Trilineares Filtering — Trilineare Filterung oder trilineare Interpolation ist eine isotrope Interpolationsmethode, die als Texturfilter beim Rendern von 3D Computergrafik zum Einsatz kommt. Bei der Trilinearen Filterung handelt es sich um eine Erweiterung der… … Deutsch Wikipedia
