摘要：
In this paper, a video data model is proposed to represent the content of video data. In the proposed model, the trajectory and other properties of objects are recorded. From the trajectory, the motion events such as "high speed" of an object and "increasing distance" between objects can be automatically derived. A query language named V-SQL based on the video data model is also proposed for the users to describe the content of the desired video clips. A graphical user interface is implemented for an easier query specification.
