Abstract

We propose a technique to control the temporal noise present in sketchy animations. Given an input animation drawn digitally, our approach works by combining motion extraction and inbetween- ing techniques to generate a reduced-noise sketchy animation regis- tered to the input animation. The amount of noise is then controlled by a continuous parameter value. Our method can be applied to ef- fectively reduce the temporal noise present in sequences of sketches to a desired rate, while preserving the geometric richness of the sketchy style in each frame. This provides the manipulation of tem- poral noise as an additional artistic parameter, e.g. to emphasize character emotions and scene atmosphere, and enables the display of sketchy content to broader audiences by producing animations with comfortable noise levels. We demonstrate the effectiveness of our approach on a series of rough hand-drawn animations.
