Abstract: We present a robust and ef´Čücient algorithm for the pairwise non-rigid registration of partially overlapped 3D sur-
faces. Our approach treats non-rigid registration as an optimization problem and solves it by alternating between
correspondence and deformation optimization. Assuming approximately isometric deformations, robust corre-
spondences are generated using a pruning mechanism based on geodesic consistency. We iteratively learn an
appropriate deformation discretization from the current set of correspondences and use it to update the corre-
spondences in the next iteration. Our algorithm is able to register partially similar point clouds that undergo large
deformations, in just a few seconds. We demonstrate the potential of our algorithm in various applications such
as example based articulated segmentation, and shape interpolation.
