Function WAVELET_2D

Package

core

Short description

Compute the wavelet transform of a signal x

Usage 

    [x_phi, x_psi] = WAVELET_2D(x, filters, options)

Input 

    x (numeric): the input signal
    filters (cell): cell containing the filters
    options (structure): options of the wavelet transform

Output 

    x_phi (numeric): Low pass part of the wavelet transform
    x_psi (cell): Wavelet coeffcients of the wavelet transform
    meta_phi (struct): meta associated to x_phi
    meta_psi (struct): meta assocaited to y_phi

Description 

    WAVELET_2D computes a wavelet transform, using the signal and the
    filters in the Fourier domain. The signal is padded in order to avoid
    border effects.
    The meta information concerning the signal x_phi, x_psi(scale, angle,
    resolution) can be found in meta_phi and meta_psi.
