The Maximal Overlap Discrete Wavelet Scattering Transform and Its Application in Classification Tasks
Leonardo Fonseca Larrubia, Pedro Alberto Morettin, Chang Chiann
We present the Maximal Overlap Discrete Wavelet Scattering Transform (MODWST), whose construction is inspired by the combination of the Maximal Overlap Discrete Wavelet Transform (…
