Wavelet packet decomposition — (WPD) (sometimes known as just wavelet packets) is a wavelet transform where the signal is passed through more filters than the DWT. In the DWT, each level is calculated by passing the previous approximation coefficients through a high and low… … Wikipedia
Wavelet — A wavelet is a mathematical function used to divide a given function or continuous time signal into different frequency components and study each component with a resolution that matches its scale. A wavelet transform is the representation of a… … Wikipedia
Wavelet — Ondelette En mathématiques, une ondelette est une fonction de carré sommable sur l espace euclidien , le plus souvent oscillante et de moyenne nulle, choisie comme outil d analyse et de reconstruction multi échelle. Les ondelettes se rencontrent… … Wikipédia en Français
Legendre wavelet — Legendre wavelets: spherical harmonic wavelets = Compactly supported wavelets derived from Legendre polynomials are termed spherical harmonic or Legendre wavelets [1] . Legendre functions have widespread applications in which spherical coordinate … Wikipedia
Second generation wavelet transform — In signal processing, the second generation wavelet transform (SGWT) is a wavelet transform where the filters (or even the represented wavelets) are not designed explicitly, but the transform consists of the application of the Lifting… … Wikipedia
Discrete wavelet transform — An example of the 2D discrete wavelet transform that is used in JPEG2000. The original image is high pass filtered, yielding the three large images, each describing local changes in brightness (details) in the original image. It is then low pass… … Wikipedia
Stationary wavelet transform — Haar Stationary Wavelet Transform of Lena The Stationary wavelet transform (SWT)[1] is a wavelet transform algorithm designed to overcome the lack of translation invariance of the discrete wavelet transform (DWT). Translation invariance is… … Wikipedia
Singular value decomposition — Visualization of the SVD of a 2 dimensional, real shearing matrix M. First, we see the unit disc in blue together with the two canonical unit vectors. We then see the action of M, which distorts the disk to an ellipse. The SVD decomposes M into… … Wikipedia
Shannon wavelet — or sinc wavelet Two kinds of Shannon wavelets can be implemented: *Real Shannon wavelet *Complex Shannon wavelet The signal analysis by ideal pass band filters define a decomposition known as Shannon wavelets (or sinc wavelets). The Haar and sinc … Wikipedia
Stéphane Mallat — Stéphane Georges Mallat ist ein französischer Elektrotechniker und Mathematiker, der wichtige Beiträge zur Wavelet Transformation leistete. Mallat studierte an der École Polytechnique (Abschluss 1984) und an der École nationale supérieure de… … Deutsch Wikipedia
Ali Akansu — Ali N. Akansu has made pioneering research contributions on the theory and applications of subband and wavelet transforms. He showed in 1989 that Binomial Quadrature Mirror Filter Bank, Binomial QMF, is identical to the celebrated Daubechies… … Wikipedia
