As you know, we use our in-house developed A.R.T. (Advanced Restoration Tools) system here at Point.360, and I brought that up here a few months ago which led to a briefly heated debate about the role of colorists vs. dedicated grain/noise processing specialists, so I'm not going to continue to harp on that. I've used every system out there, as well as working with and developing prototype algorithms not yet available in any commercial products. Next to A.R.T., I do quite like the Revival/Resolve tools, Neat is good, but I've been quite interested lately in research and methods using kernel regression algorithms as opposed to wavelet processing...
