Abstract

This thesis investigates the current state-of-the-art in registration of non-rigidly deforming shapes. In particular, the problem of non-isometry is considered. First, a method to address locally anisotropic deformation is proposed. The subsequent evaluation of this method highlights a lack of resources for evaluating such methods. Three novel registration/shape correspondence benchmark datasets are developed for assessing different aspects of non-rigid deformation. Deficiencies in current evaluative measures are identified, leading to the development of a new performance measure that effectively communicates the density and distribution of correspondences. Finally, the problem of transferring skull orbit labels between scans is examined on a database of unlabelled skulls. A novel pipeline that mitigates errors caused by coarse representations is proposed.
