Point set registration (PSR) is an essential problem in the field of surgical navigation and augmented reality (AR). In navigation, aim mapping pre-operative space to intra-operative space. This article introduces a reliable hybrid mixture model, which reliability normal vectors generalized point (GPS) examined exploited. The motivation considering orientation information that cannot be estimat...

An unsupervised iterative N-dimensional point-set registration algorithm for unlabeled data (i.e., the correspondence between points is unknown) based on linear least squares proposed. The considers all possible point pairings and iteratively aligns two sets until number of pairs does not exceed maximum allowable one-to-one pairings.
