They pose similar problems at the object modeling level. The Visual Modeling research program takes a unified approach to vision and graphics through the apparatus of computational physics. In this talk I shall focus on physically-based, deformable models and associated force field techniques for synthesizing and analyzing the shapes and motions of nonrigid objects. I will demonstrate the application of deformable models to vision problems such as adaptive image sampling, image contour extraction, stereo and motion estimation, visible-surface and 3D object reconstruction, and the recovery of 3D shape and nonrigid motion of objects from dynamic stereo imagery. The video presentation will also include computer graphics animation of deformable models illustrating a variety of behaviors in simulated physical worlds, along with a recent application: physically- based modeling and interactive animation of the human face.
