摘要: This paper proposed novel techniques in spatial reasoning and similarity retrieval for pictorial information systems using spatial relations among spatial objects in vector-based representation. Three types of spatial reasoning were investigated in this paper: inverse reasoning, transitive reasoning, and abstraction-specialization exchange reasoning. Spatial reasoning makes the system become more intelligent. Based on different accuracy requirements, spatial relations can be categorized into two layers.This two-layer approach allows the system to retrieve pictures from a pictorial database in a more flexible way.
