Re-using Traditional Animation: Methods for Semi-Automatic Segmentation and Inbetweening

Abstract
A large body of traditional animation exists that contains characters
with poses, expressions, and appeal not easily achievable with modern
3D techniques. To create new uses for this body of animation, this
paper presents components of a system that can help incorporate the
animation into re-usable libraries. In particular, we discuss two
semi-automatic techniques that allow the re-use of traditional
animation. First, support vector machines are used to segment cartoon
images from their backgrounds for incorporation into an image library,
for such applications as re-sequencing. Second, a radial basis
function implicit surface modeling technique and a fast non- rigid
elastic registration algorithm provide inbetween contours and textures
given two key images of traditional animation. Our system is fast,
model-free, and requires minimal animator intervention.
