“Cartoon Morphing and Animation with Wavelet Curve Descriptor”
by Gene C.-H. Chuang and C.-C. Jay Kuo
April 1995
We present a hierarchical curve descriptor which decomposes a planar curve into components of different scales by using the wavelet transform, and examine the application of the wavelet descriptor to cartoon character morphing and animation. A procedure to eliminate the undesirable self-intersection phenomenon in the morphing process is described. For animation, we model the motion of a cartoon character with the Lagrangian dynamic equation whose mass and stiffness matrices are greatly simplified via wavelet transform. As a consequence, the model parameters can be extracted and the animation procedure can be implemented very effectively.
