Abstract
Aspect graphs are well known multiview object representations employed in object recognition tasks. Polyhedra in many applications have shown to be adequate approximative models for real — especially man-made — objects. Aspect graphs of polyhedral objects are generated by a structural analysis of the observed object to derive the visual events which define the partitioning surfaces of the viewing space into regions showing the same object appearance. The kinds of visual events used within this analysis are defined by polyhedral surfaces, vertex-edge pairs and triples of edges. We have found a new type of visual event which is defined by pairs of edges and is not mentioned explicitly in all other approaches on this topic. We show that the exhaustive list of types of visual events derived in our approach is complete and that the new edge-edge event is not a special case of the other well known visual events of polyhedral scenes.
