neat video optimised for cleaning cgi renders?
Posted: Sat Aug 31, 2013 3:05 pm
CGI these days is moving towards more accurate simulation of light (mainly through variations of monte-carlo pathtracing), which as a by-product results in noisy renders.
We've been using Neat Video to help us clean up renders, and its been working very well, however we've been seeing some interesting research papers on denoising renders using information provided 'for free' from the render engine.
Is this something Neat Video would be interested in persuing?
Specifically, Neat Video is only aware of the input video stream. Because in 3D rendering we can provide MUCH more information about each pixel, and break that info out into separate image sequences, it seems possible that this could be used to do more accurate noise removal, and require less computation. For example, we can easily provide information about where each pixel is in space, how fast its moving, its texture independant from light and shadow, its angle relative to camera, its shadow component, masks for where there's important edge detail etc.
Here's some videos and papers that go into more detail.

Noise in pathtracers is a big problem in CG, Neat Video could become an even more popular tool if it came up with a good solution!
