Integration of quantitative and qualitative techniques for deformable model fitting from orthographic, perspective, and stereo projections

In this paper, we .synthesize a new approach to 3-0 object shape recovery b y integrating qualitative shape recovery techniques and quantitative physicsbased shape estimation techniques. Specifically, we ,first use qualitative shape recovery and recognition techniques to provide strong fitting constraints on physics-based deformable model recovery techniques. Secondly, we extend our previously developed technique of fitting deformable models to occluding image contours to the case of image data captured under general orthographic, perspective, and stereo projections.
