Path following algorithm for matching partially overlapping feature sets

Abstract

To address feature matching problem where there is only partial overlap between the two feature sets, minimisation of an energy function consisting of feature matching costs and a concave regularisation term capable of handling partial overlaps is proposed. To improve robustness to disturbances, a path following strategy for minimisation which dynamically combines weights of the two terms is adopted. Experimental results verify better performance of the method over several state-of-the-art methods.
