Utilizing symmetry in the reconstruction of three-dimensional shape from noisy images
In previous applications, bilateral symmetry of objects was used either as a descriptive feature in domains such as recognition and grasping, or as a way to reduce the complexity of structure from motion. In this paper we propose a novel application, using the symmetry property to \symmetrize" data before and after reconstruction. We rst show how to compute the closest symmetric 2D and 3D con gurations given noisy data. This gives us a symmetrization procedure, which we apply to images before reconstruction, and which we apply to the 3D conguration after reconstruction. We demonstrate a signi cant improvement obtained with real images. We demonstrate the relative merits of symmetrization before and after reconstruction using simulated and real data.
