numfilterbanks

R2026b

Number of filter banks in wavelet time scattering network

Syntax

nfb = numfilterbanks(sf)

Description

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

Examples

Number of Filter Banks in Wavelet Scattering Network

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

sf = waveletScattering

sf = 
  waveletScattering with properties:

          SignalLength: 1024
       InvarianceScale: 512
        QualityFactors: [8 1]
              Boundary: 'periodic'
     SamplingFrequency: 1
             Precision: 'double'
    FilterDownsampling: 'fullband'
    OversamplingFactor: 0
          OptimizePath: 0

Nfb = numfilterbanks(sf)

Nfb = 
2
