In this paper, we propose a video semantic model to get the higher-level semantics of spatial relation changes between the objects in a video represented by a 3D C-string, which represents the lower-level information of spatio-temporal relations, motions and size changes of the objects in a video. We use the concept of finite automata to record the transitions of objects' spatial relations. From the final states of the finite automaton, the higher-level semantics of spatial relation changes between the objects in a video can be inferred. ? 2008 IEEE.3D C-stringSpatial relationVideo content managementVideo semantic modelconference paper10.1109/ICICIC.2008.652-s2.0-52449116818https://www.scopus.com/inward/record.uri?eid=2-s2.0-52449116818&doi=10.1109%2fICICIC.2008.65&partnerID=40&md5=214aa7614a812b8fe05b5ddae78830c3
