Processing video to appear like a cartoon presents us with two distinct problems. First we must work out how to paint strokes that are stable in time, otherwise the video appears to “flicker”. Second we must add “streak-lines”, “squash-and-stretch” effects, “anticipation” and all of the other effects real animators routinely use. This work solved both problems.
We were the first to show how to paint over video in a stable way. Our solution allows painting in many styles. Sometimes artists want an incoherent effect, provided they can control it; we provide that level of control. In fact artists can map animated paintings into regions, replace background and generally have real control over their output.
Another first for this work is the introduction of cartoon effects: streak-lines and so on. These effects require a significant change to the video content - balls that look real seem to stretch as they fly through the air and squash when they bounce.
