Modeling of video spatial relationships in an object database management system
Jingjing Li, M. TAMER ÖZSU, Duane Szafron · 2002
A key aspect in video modeling is spatial relationships. We propose a spatial representation for specifying the spatial semantics of video data. Based on such a representation, a set of spatial relationships for salient objects is defined to support qualitative and quantitative spatial properties. The model captures both topological and directional spatial relationships. We present a novel way of incorporating this model into a video model, and integrating the abstract video model into an object database management system which has rich multimedia temporal operations. The integrated model is further enhanced by a spatial inference engine. The powerful expressiveness of our video model is validated by some query examples.
