Abstract :
The authors synthesize a new approach to 3-D object shape recovery by integrating qualitative shape recovery techniques and quantitative physics-based shape estimation techniques. They first use qualitative shape recovery and recognition techniques to provide strong fitting constraints on physics-based deformable model recovery techniques. Previously developed techniques of fitting deformable models to occluding image contours are then extended to the case of image data captured under general orthographic, perspective, and stereo projections. Experimental results are presented to illustrate the shape recovery approach
