Spatio-temporal Reasoning by Combined Topological and Directional Relations Information
Résumé
Spatio-temporal reasoning is extensively used in many areas of computer vision and Artificial Intelligence. Different models for spatio-temporal reasoning are proposed based on topological and directional relations sepa- rately in respective domains. Reasoning about moving objects in a spatial scene or description about the two-dimensional scene needs both the reasoning systems simultaneously. We introduced a reasoning system of a two-dimensional spatial scene based on Combined Topological and Directional(CTD) relations method, where we obtain both topological and orientation information simul- taneously. Entities in composite tables follows the certain mathematical rule, these rules are elaborated through the certain examples and the composition table for topological relations are rearranged and divided into sub-tables.
