Paper Abstract

We propose here a pre-processing of 3D shapes which allows to give greater importance to the match between some parts of the surface of one object and some parts of the surface of the other object during the matching of the two objects. The method is working with objects defined on a digital grid and consists in a segmentation step to separate the main components of the shapes, and in a distance computation step to determine matching weights to be assigned to the surface points. Several new algorithms are developed: a 3D segmentation algorithm based on mathematical morphology, a fast method to compute geodesic distances on a 3D surface, a simple sphere creation algorithm on a digital grid. The method has been applied to chemical molecules.
