A rule based approach for pattern recognition in planar geometric figures

Abstract An OPS5 expert system has been developed, allowing the recognition of an arbitrary subpattern in a complex planar geometric figure under analysis. For this sake a syntactic representation for images is used by the expert system as a relational data base. The expert system looks for consistent mappings of the set of topological elements/relations representing the given subpattern into a corresponding subset of the topological elements/relations representing the geometric figure under analysis....
