A Novel Canonical Form for the Registration of Non Rigid 3D Shapes

In this paper, we address the problem of non rigid 3D shapes registration. We propose to construct a canonical form for the 3D objects corresponding to the same shape with different non rigid inelastic deformations. It consists on replacing the geodesic distances computed from three reference points of the original surface by the Euclidean ones calculated from three points of the novel canonical form. Therefore, the problem of non rigid registration is transformed to a rigid matching between canonical forms. The effectiveness of such method for the recognition and the retrieval processes is evaluated by the experimentation on the TOSCA database objects in the mean of the Hausdorff Shape distance.
