Here are some results showing noise reduction of raytraced sources.   It’s an improved revision of the experiments we tried previously... The first movie is basically a split showing the original and the noise reduced result.  It works best to play it full screen, at low quality (which should disable any post filtering).  Unfortunately, the compression used to make this playable over the internet tends to minimize the noise, so you have to look very closely.

Note: these are larger than most of our downloads because the compression is mild.

This next movie is a crop from the first, prior to compression.  It has had a Laplacian filter applied and normalized.  It shows the noise much more clearly.

Finally, the same clips run through a small composite which sets the final “look”.

We employed a similar technique with a different subject matter.   This can play full screen nicely.
