Content-based retrieval using trajectories of moving objects in video databases
Choon-Bo Shim, Jae‐Woo Chang · 2001
In this paper, we propose a new spatio-temporal representation scheme for modeling multiple moving objects' trajectories in video databases. For content based video retrieval on moving objects efficiently, our representation scheme considers the moving distance of an object during a given time interval as well as its temporal and spatial relationships. We present a similarity measure algorithm for the multiple moving objects' trajectories
