摘要：
The trajectory of moving objects in video data plays an important role in video indexing for content-based retrieval. In this paper, we propose a new spatio-temporal representation scheme for modeling moving objects' trajectories in video data. In order to support content-based retrieval on video data very well, our representation scheme considers the moving distance of an object during a given time interval as well as its temporal and spatial relations. Based on our representation scheme, we present two similarity measures for both the trajectory of a single moving object and those of multiple moving objects, which provide ranking for the retrieved video results. Finally, we show from our experiment that our representation scheme achieves about 10-20% higher precision while it holds about the same recall, compared with its competitors, such as Li's and Shan's schemes.
