Wavelets

Some articles on wavelets, wavelet:

Legendre Wavelet
... Compactly supported wavelets derived from Legendre polynomials are termed spherical harmonic or Legendre wavelets ... As with many wavelets there is no nice analytical formula for describing these harmonic spherical wavelets ... Wavelets associated to finite impulse response filters (FIR) are commonly preferred in most applications ...
Beta Wavelet
... Continuous wavelets of compact support can be built, which are related to the beta distribution ... These new wavelets have just one cycle, so they are termed unicycle wavelets ... They can be viewed as a soft variety of Haar wavelets whose shape is fine-tuned by two parameters and ...
Harmonic Wavelet Transform - Harmonic Wavelets
... The transform uses a family of "harmonic" wavelets indexed by two integers j (the "level" or "order") and k (the "translation"), given by, where These ... As the order j increases, these wavelets become more localized in Fourier space (frequency) and in higher frequency bands, and conversely become less localized in time (t) ... function φ is orthogonal to itself for different k and is also orthogonal to the wavelet functions for non-negative j ...
MATLAB Implementation of Legendre Wavelets
... Legendre wavelets can be easily loaded into the MATLAB wavelet toolbox -- The m-files to allow the computation of Legendre wavelet transform, details and filter are (freeware) available ... Wavelets 'legdN' ... Legendre wavelets can be derived from the low-pass reconstruction filter by an iterative procedure (the cascade algorithm) ...
Lifting Scheme - Applications
... Wavelet transform with integer values WAILI Fourier transform with bit-exact reconstruction Soontorn Oraintara, Ying-Jui Chen, Truong Q ... Integer Fast Fourier Transform Construction of wavelets with a required number of smoothness factors and vanishing moments Construction of wavelets matched to a given pattern Henning Thielemann ...

Famous quotes containing the word wavelets:

    Broken by great waves,
    the wavelets flung it here,
    this sea-gliding creature,
    this strange creature like a weed....
    Hilda Doolittle (1886–1961)
