NoMoSmooth (motion-adaptive spatio-temporal smoother)

Motion detector 

New version 

Yes, it's time again to put my head on the block and see what comes a-swingin' ;). Here's 0.0c, still proof of concept (source available here). It incorporates the abovementioned motion detector, with temporal smoothing applied to static areas and spatial smoothing to areas in motion. While the motion detection algorithm is optimized (runs near real-time at 720x480 on my system) the smoothers aren't (and don't), with the spatial smoother being especially slow. This will be fixed if there's interest in me doing so. Other caveats are it passes through pixels within spatial_radius of the edges and frames within temporal_radius of the ends of the clip. See the for more information and usage. Here we go again... :) Edit: Removed links to old version.

My observations so far: It seems more tolerant of higher temporal settings (both radius and threshold) than spatial. High spatial settings (particularly threshold) seem to produce much more noticible artifacts. Increasing caching with SetMemoryMax seems to increase speed, especially with a higher temporal radius. Comments and suggestions always welcome :).
