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

Cohen-Daubechies-Feauveau-Wavelet — Cohen Daubechies Feauveau Wavelets (CDF Wavelets) sind die historisch gesehen erste Familie der biorthogonalen Wavelets. Sie wurden von Albert Cohen, Ingrid Daubechies und Jean Christophe Feauveau konstruiert und 1990 vorgestellt.[1] CDF Wavelets … Deutsch Wikipedia
Orthogonal wavelet — An orthogonal wavelet is a wavelet where the associated wavelet transform is orthogonal. That is the inverse wavelet transform is the adjoint of the wavelet transform. If this condition is weakened you may end up with biorthogonal wavelets.… … 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
