Abstract:

On the basis of intersection matrix representation, we established a model representing the topological relation  between concave region and simple broad boundary region. Three constraints were proposed that are reasonable, from which 67 topological relations that are realizable in 2D space were derived.

Key words: artificial intelligence, concave region, simple broad boundary region
