Discrete wavelet transform
In numerical analysis and functional analysis, a discrete wavelet transform is any wavelet transform for which the wavelets are discretely sampled.
Continuous wavelet transform
In mathematics, the continuous wavelet transform is a formal (i.e., non-numerical) tool that provides an overcomplete representation of a signal by letting the translation and scale parameter of the wavelets vary continuously.
Fast wavelet transform
The fast wavelet transform is a mathematical algorithm designed to turn a waveform or signal in the time domain into a sequence of coefficients based on an orthogonal basis of small finite waves, or wavelets.
Complex wavelet transform
The complex wavelet transform is a complex-valued extension to the standard discrete wavelet transform.
