In mathematics, the Fourier transform (FT) is an integral transform that takes a function as input then outputs another function that describes the extent...

Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). A Fourier transform converts...

In mathematics, the Laplace transform, named after Pierre-Simon Laplace (/ləˈplɑːs/), is an integral transform that converts a function of a real variable...

A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies...

the Fourier transform, is often given a more specific name, which depends on the domain and other properties of the function being transformed. Moreover...

A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly horizontal. It ends abruptly where it connects...

In mathematics, the discrete Fourier transform (DFT) converts a finite sequence of equally-spaced samples of a function into a same-length sequence of...

to the frequency domain usually through use of the Fourier transform. The Fourier transform converts the time or space information to a magnitude and phase...

Extract, transform, load (ETL) is a three-phase computing process where data is extracted from an input source, transformed (including cleaning), and loaded...

domains with a pair of mathematical operators called transforms. An example is the Fourier transform, which converts a time function into a complex valued...

In mathematics, an integral transform is a type of transform that maps a function from its original function space into another function space via integration...

discrete wavelet transform (DWT) is any wavelet transform for which the wavelets are discretely sampled. As with other wavelet transforms, a key advantage...

mathematical definition of an orthonormal wavelet and of the integral wavelet transform. A function ψ ∈ L 2 ( R ) {\displaystyle \psi \,\in \,L^{2}(\mathbb {R}...

analysis, visualization and data preprocessing. The data is linearly transformed onto a new coordinate system such that the directions (principal components)...

Fourier transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas...

Transform coding is a type of data compression for "natural" data like audio signals or photographic images. The transformation is typically lossless...
