hmmmm....there is a program called deBabelizer that I got many (5? 6?) years ago, that not only does wonders converting between just about every possible graphics file format, but also handles movie/animation formats. In it, you can apply Photoshop filters on a frame-by-frame basis, or can do automated batch processing. I imagine that using a Photoshop 'posterize' and/or 'find edges' effect that this can be accomplished. (searching, searching....ah, here it is....) Equilibrium is the company. They're up to version 6 currently, but you may be able to find an earlier (ie, cheaper) version at Ebay or Amazon.
