[Bf-committers] Possible Render Noise Filter?

[Jason W.]

Has anyone evaluated this paper?

Seems like a potential addition to either cycles viewport rendering and/or a couple of compositor node.  It takes as few as 8 samples per pixel and is comparable with many many times more for about 3 times the computation of 8spp. It preserves detail and edges well.  Not sure what the additional memory use would be.
