Proposes a framework for cartoon animation and morphing by using a hierarchical planar curve descriptor based on the wavelet transform. To facilitate the animation task, the authors first model the motion of curves with the Lagrangian dynamic equation where the multiscale curve is driven by internal and external forces. The spatial and frequency localization property of the wavelet representation results in a virtually decoupled Lagrangian equation and, as a result, the computation is greatly simplified. The motion parameters, which contain the kinematic information of the control points, are extracted from motions of real video images. They are then used to generate motion sequences of similar nature. The authors also examine a highly automatic algorithm for non-self-intersecting contour morphing. Experiments of the proposed algorithms are conducted to demonstrate their performance.<>
