Improvement of modal matching image objects in dynamic pedobarography using optimization techniques

Abstract

The paper presents an approach for matching objects in dynamic pedobarography image sequences, based on finite element modeling and modal analysis. The determination of correspondences between objects nodes is here improved using optimization techniques and, because the elements number of each object is not necessarily the same, a new algorithm to match excess nodes is proposed. This new matching algorithm uses a neighborhood criterion and can overcome some disadvantages that the usual matching one to one in various applications can have. The proposed approach allows the determination of correspondences between 2D or 3D objects and will be here considered in dynamic pedobarography images.
