Abstract

We analyze the most difficult case of visual surveillance, when people in motion are observed by a moving camera. Our solution to this problem is a hybrid system that combines the online 3D reconstruction of stationary background structure, camera trajectory, and moving foreground objects with more established techniques in the 2D domain. Once this 3D part has succeeded in focusing the attention on a particular, moving foreground object, we continue in the 2D image domain using a state-of-the art shape-based person detector, and meanshift-based object tracking. Our results show various benefits of this hybrid approach beyond improved detection rate and reduced false alarms. In particular, each individual algorithmic component can benefit from the results of the other components, by gathering a richer foreground description, improved self-diagnosis capabilities, and by an explicit use of the available 3D information.
