%X Region connection calculus (RCC) is one of the important fundamental theories in qualitative spatial reasoning (QSR). Lacking necessary metrization, RCC only describe spatial topological relations roughly without further accurateness, and it is also not easy to describe spatial relations such as distance, direction and so on, with the exclusion of topological relation. Based on the RCC theory, Region Extension and Shrinking Calculus (RESC) is proposed. As for RESC, the congruence CG as a primitive spatial r...
