Function WAVELET_FACTORY_2D

Package

Short description

Usage

    [Wop, filters] = WAVELET_FACTORY_2D(size_in, filt_opt, scat_opt)

Input

    size_in (numeric): The size of the signals to be transformed.
    filt_opt (structure): The filter options, same as for 
       MORLET_FILTER_BANK_2D or SHANNON_FILTER_BANK_2D
	 scat_opt (structure): The scattering and wavelet options, identical to
       WAVELET_LAYER_1D/WAVELET_1D.

Output

    Wop (cell of function handle): A cell array of wavelet transforms 
    required for the scattering transform.
    filters (cell): A cell array of the filters used in defining the wavelets.

Description

    NOTE : A faster implementation is avaible as WAVELET_FACTORY_2D_LAYER.
    This function create a cell array of linear operators that will be
    used for the successive wavelet transforms. Here, only the morlet
    filter bank is used.
    If M, the number of layer, is not specified, its value is set automatically to 2.
