Three-Valued 9-Intersection for Deriving Possible Topological Relations from Incomplete Observations
14 years 7 months ago
Topological relations, which concern how two objects intersect, are one of the most fundamental and well-studied spatial relations. Typically, topological relations are distinguis...
