Fix decimation at order 2 or more in the transform. #43

Open blasscoc opened 5 years ago

blasscoc commented 5 years ago

Looks like we need to decimate first round, as we are by the scale of the wavelet.

But in higher orders, we decimate by the difference in scales, see: https://github.com/kymatio/kymatio/blob/master/kymatio/scattering2d/scattering2d.py

for an example.

Change the decimation to match the MATLAB/Kymatio implementation.
