The concept of systems of the same type is given, their homomorphic mapping and isomorphic mapping are introduced simultaneously, and the induced system of a given system is defined. Then the connection of homomorphism (isomorphism) between systems of the same type and their induced systems is proved by mapping function. In addition, homomorphism (isomorphism) invariant properties, total automorphism...
As we move increasingly towards multi-source data analysis, the assessment of similarity of complex, multilayer scenes is becoming increasingly important for spatial data mining. In this paper, we present a content-based approach for scene similarity assessment. The proposed approach is based on a graph-matching scheme that models linear feature networks (road network) as graphs and additional GIS...
