numfilterbanks

Number of scattering filter banks

Syntax

nfb = numfilterbanks(sf)

Description

nfb = numfilterbanks(sf) returns the number of filter banks in the wavelet image scattering network, sf. The number of filter banks in the network is equal to ord − 1 where ord is the number of scattering orders.

Examples

Number of Filter Banks in 2-D Wavelet Scattering Network

Calculate the number of filter banks for the default 2-D wavelet scattering network.

sf = waveletScattering2

sf =
