  • Wavelet compression — is a form of data compression well suited for image compression (sometimes also video compression and audio compression). The goal is to store image data in as little space as possible in a file. Wavelet compression can be either lossless or… …   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 transform — An example of the 2D discrete wavelet transform that is used in JPEG2000. In mathematics, a wavelet series is a representation of a square integrable (real or complex valued) function by a certain orthonormal series generated by a wavelet …   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

  • Daubechies wavelet — Daubechies 20 2 d wavelet (Wavelet Fn X Scaling Fn) Named after Ingrid Daubechies, the Daubechies wavelets are a family of orthogonal wavelets defining a discrete wavelet transform and characterized by a maximal number of vanishing moments for… …   Wikipedia

  • Haar wavelet — ] >The Haar wavelet is the first known wavelet and was proposed in 1909 by Alfréd Haar [Haar, Alfred; Zur Theorie der orthogonalen Funktionensysteme. (German) Mathematische Annalen 69 (1910), no. 3, 331 371.] . Haar used these functions to give… …   Wikipedia

  • Continuous wavelet transform — of frequency breakdown signal. Used symlet with 5 vanishing moments. A continuous wavelet transform (CWT) is used to divide a continuous time function into wavelets. Unlike Fourier transform, the continuous wavelet transform possesses the ability …   Wikipedia

  • 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

  • Cohen-Daubechies-Feauveau wavelet — For other uses of CDF , see CDF (disambiguation). An example of the 2D wavelet transform that is used in JPEG2000 Cohen Daubechies Feauveau wavelet are the historically first family of biorthogonal wavelets, which was made popular by Ingrid… …   Wikipedia
