Abstract:
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.
