Berger, and J. E . Cinemania and the Internet Movie Database are query only systems. 280291, Feb. 1995. In this tool, camera motion such as zoom in and zoom out can be also specified. The retrieved set of video sequences will have all similar objects moving in the similar direction, with similar camera movements.
Recent efforts begin to address query languages involving images, video, audio and text.
Typical applications are automated surveillance systems, industrial monitoring, road traffic monitoring, video databases etc. Most research in this area focuses on tracking the movement of single object, i.e. the trajectory of an object over a period of time, which is certainly very important. A bitemporal relation, including both event time and database time, is applied to objects in the system. This model is designated for GISs. We do not consider such kind movement in this paper.
