Function WAVELET_LAYER_3D

Package

Short description

Usage

   [U_Phi, U_Psi] = WAVELET_LAYER_3D(U, filters, filters_rot, options)

Input

   U (struct): input scattering layer
   filters (struct): 2d filter bank to apply along spatial variable
   filters_rot (struct): 1d filter bank to apply along orientation
   options (struct): same as wavelet_3d

Output

   U_Phi (struct): low pass convolutions of all signal of layer U
   U_Psi (struct): high pass convolutions of all signal of layer U

Description

   This function will compute all the roto-translation wavelet transform
   of signals contained in the input layer U. If the previous layer
   is contains only 2d signal, it starts by extracting rotation orbits.
   It then forward each orbit to WAVELET_3D that will process them
   independantly.
