Abstract :
A vision system based on the attributed hypergraph representation (AHR) and monomorphism is presented. The graph representation consists of the structural descriptions of the objects in a scene and their interrelations. It renders all structural information explicit and symbolic. A hypergraph monomorphism algorithm is then used to compare the AHR of objects in the scene with a set of complete AHRs of prototypes. It enables objects which may be partially occluded by each other to be distinguished
