Spectral efficiency — Spectral efficiency, spectrum efficiency or bandwidth efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently a limited frequency spectrum is… … Wikipedia
Spectral sequence — In the area of mathematics known as homological algebra, especially in algebraic topology and group cohomology, a spectral sequence is a means of computing homology groups by taking successive approximations. Spectral sequences are a… … 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
Bayesian spam filtering — (pronounced BAYS ee ən, IPA pronunciation: IPA| [ beɪz.i.ən] , after Rev. Thomas Bayes), a form of e mail filtering, is the process of using a naive Bayes classifier to identify spam e mail.The first known mail filtering program to use a Bayes… … Wikipedia
Eilenberg-Moore spectral sequence — In mathematics, in the field of algebraic topology, the Eilenberg Moore spectral sequence addresses the calculation of the homology groups of a pullback over a fibration. The spectral sequence formulates the calculation from knowledge of the… … Wikipedia
Mamyshev 2R regenerator — The Mamyshev 2R regenerator is an all optical regenerator used in optical communications. In 1998, Pavel V. Mamyshev of Bell Labs proposed and patented the use of the self phase modulation (SPM) for single channel optical pulse reshaping and re… … Wikipedia
Ultrafast monochromator — In the diffraction of an ultrashort pulse (in the femtosecond, or lower, time scale) with a grating,apart spectral filtering, there occurs a time stretching due to the difference in the path length among the rays diffracted, even of equal… … Wikipedia

Image fusion — In computer vision, Multisensor Image Fusion is the process of combining relevant information from two or more images into a single image. The resulting image will be more informative than any of the input images. In remote sensing applications,… … Wikipedia
analysis — /euh nal euh sis/, n., pl. analyses / seez /. 1. the separating of any material or abstract entity into its constituent elements (opposed to synthesis). 2. this process as a method of studying the nature of something or of determining its… … Universalium
