Abstract. Robust object tracking is required by many vision applications, and it will be useful for the motion analysis of moving object if we can not only track the object, but al...
Abstract. In this paper, we describe an unsupervised learning framework to segment a scene into semantic regions and to build semantic scene models from longterm observations of mo...
—In this demonstration paper, we present a powerful distributed framework for finding similar trajectories in a smartphone network, without disclosing the traces of participatin...
Abstract. A prototype basketball video retrieval system is presented in this report. Retrieval is based on the similarity of ball motion in the clip with that in the query. The sys...
