Abstract

Point set registration is the key in many scientific disciplines. Target at several challenges in registration (e.g. initial registration, outliers, missing data, and local trap), we propose a robust registration method for two point sets using a hierarchical Bayesian model, which is combined with Markov chain Monte Carlo inference. Our approach is based on the introduction of a template of hidden locations underlying the observed configuration points. A Poisson process prior is assigned to these locations, resulting in a simplified formulation of the model. We make use of a structure containing the relevant information on the matches. We conduct several experiments to demonstrate that our algorithm is accurate and robust.
