Function WAVELET_FACTORY_3D

Package

Short description

Usage

   [Wop, filters, filters_rot] = WAVELET_FACTORY_3D(size_in, filt_opt, filt_rot_opt, scat_opt)

Input

    size_in (2x1 int): the size of the image to be transformed
    filt_opt (struct): the filter options, same as for MORLET_FILTER_BANK_2D 
    filt_rot_opt (struct): the filter options for the 
		filters along angular parameter, same as for MORLET_FILTER_BANK_1D 
	 scat_opt (struct): the scattering and wavelet options, same as

Output

    Wop: A cell array of wavelet transforms needed for the scattering trans-
       form.
    filters: A cell array of the filters used in defining the wavelets.

Description

   This function builds the wavelet operators used to compute the 
   roto-translation scattering. The first operator is a 2d wavelet
   transform obtained with WAVELET_LAYER_2D. The second operator and third
   operators are roto-translation wavelet transform obtained with
   WAVELET_LAYER_3D.
