In this paper, we present a technique we call "cartoon capture and retargeting" which we use to track the motion from traditionally animated cartoons and retarget it onto 3-D models, 2-D drawings, and photographs. By using animation as the source, we can produce new animations that are expressive, exaggerated or non-realistic.Cartoon capture transforms a digitized cartoon into a cartoon motion representation. Using a combination of affine transformation and key-shape interpolation, cartoon capture tracks non-rigid shape changes in cartoon layers. Cartoon retargeting translates this information into different output media. The result is an animation with a new look but with the movement of the original cartoon.

O ur goal is to em bed free-form constraints into a graphical m odel. W ith such constraints a graphic can m aintain its visual integrity— and break rules tastefully— while being m anipulated by a casualuser. A typicalparam eterized graphic does notm eet these needs because its configuration space contains nonsense im ages in m uch higher proportion than desirable im ages, and the casual user is apt to ruin the graphic on any attem pt to m odify oranim ate it.
