Function WAVELET_FACTORY_2D_PYRAMID

Package

Short description

Usage

    [Wop, filters] = WAVELET_FACTORY_2D_PYRAMID(filt_opt, scat_opt)

Input

    filt_opt (struct): the filter options, same as for MORLET_FILTER_BANK_2D_PYRAMID 
	 scat_opt (Struct): the scattering and wavelet options, same as WAVELET_2D_PYRAMID
       with an additonal optional field 
           M (int) : the number of layer of the scattering transform

Output

    Wop (cell of function_handle): contains the wavelet transforms to
       apply during scattering computation
    filters (struct): a 2d filter bank

Description

   This function builds the operators to be apply during scattering
   computation, in this case 2d wavelet transform. The implementation of
   the 2d wavelet transform used here is faster than those provided by
   WAVELET_FACTORY_2D.
