(signal processing) A generalized Fourier transform that performs an orthogonal, symmetric, involutive, linear operation on 2ᵐ real numbers (or complex numbers, although the Hadamard matrices themselves are purely real).

(mathematics) An integral transform closely related to the Fourier transform, but which transforms real-valued functions to real-valued functions.

Synonym of Hadamard transform

A feature extraction technique used in computer vision and digital image processing to find imperfect instances of objects within a certain class of shapes by a voting procedure.

plural of transform fault

(mathematical analysis, number theory, statistics) An integral transform that may be regarded as the multiplicative version of the two-sided Laplace transform.

A member of a certain family of algorithms for efficiently computing the discrete Fourier transform of data. / An instance of performing one of these algorithms.

(mathematics) A mathematical operation that transforms a function for a discrete or continuous spectrum into a function for the amplitude with the given spectrum; an inverse transform of the Fourier transform.

An algorithm used in data compression that rearranges a character string into runs of similar characters.
