Modeling of moving objects and querying videos by trajectories
Yan Jianfeng, Zhanhuai Li · 2004
Content-based retrieval of videos in databases is a technique which has attracted considerable research interest during the last years (Guojun, 1999). Most papers in this area discuss how to retrieve some kinds of video scenes involving moving objects according to some example trajectories of these objects according to Nabil (1998) and Aghbari et al. (2000). In this paper, we present a model to describe the trajectories of moving objects and use it to retrieve video scenes.
