Function WAVELET_LAYER_2D

Package

core

Short description

Compute the wavelet transform of a scattering layer

Usage 

    [U_phi, U_psi] = WAVELET_LAYER_2D(U, filters, options)

Input 

    U (struct): input scattering layer
    filters (struct): filter bank 
    options (struct): same as wavelet_2d

Output 

    A (struct): Averaged wavelet coefficients
    V (struct): Wavelet coefficients of the next layer

Description 

    This function has a pivotal role between WAVELET_2D (which computes a
    single wavelet transform), and WAVELET_FACTORY_2D (which creates the
    whole cascade). Given inputs modulus wavelet coefficients
    corresponding to a layer, WAVELET_LAYER_2D computes the wavelet
    transform coefficients of the next layer using WAVELET_2D.
