Video analysis for Cartoon-style Special Effects

In recent years the Vision community has shown interest in processing images and video for use by the entertainment industries. Typical applicationsinclude 3D reconstruction of models, and rendering graphics models into video. This paper broadly aligns with that trend, but differs in that we process video to emphasise motion in Cartoon-like styles, in which moving objects deform in defiance of physical laws, and leave trailing marks of one kind or another in their wake. We provide an introduction to the effects real animators use, and show how a judicious choice of standard processing techniques, supplemented by novel methods, can be used to achieve convincing results. We illustrate the robustness of our method using several video sequences, ranging in content from simple oscillatory to articulated motion, under both static and moving camera conditions.
