Any plans to explore using sinc filter for downsampling?

Awesome work.

Take a look at alias-free gan by Nvidia if you haven't already.

The filters in this research only reduce alias by smoothing but using a sinc kaiser filter like alias-free gan can almost completely remove aliasing. It will be very interesting to see how the network performs.

Yes, that's a great paper! I think better filters should indeed help
