(category theory) A morphism between a pair of parallel functors such that if each object of the shared domain category subtends a correlated arrow — called a component — in the shared codomain (which arrow represents the difference between applying the second functor and the first functor to the correlated object) then each arrow of the shared domain subtends a commuting square — called a naturality square — between two components (correlated to the domain and codomain of the arrow).

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 transformational grammar

plural of Laplace transform

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

(mathematics) A transform that converts a discrete time-domain signal into a complex frequency-domain representation.
