Abstract
This paper presents a physics-based approach for recoveringthe 3D shape and tracking the motion of nonrigid objectsusing a 3D elastically deformable balloon model. Theballoon model is based on a thin-plate under tension splinewhich deforms to fit visual data according to internal forcesstemming from the elastic properties of the surface and externalforces which are produced from the data. We employthe finite element method to represent the model as a continuoussurface. We use a...Keywords
