An integrated surveillance system for outdoor security

An integrated system for the detection, active tracking and recognition of people in wide outdoor environments is hereafter discussed. Specifically, a static sensor with a wide view is used to detect people inside the environment and to classify their behaviours. As outcome of anomalous activities, an active camera is selected to focus its attention on a particular person. Here, techniques for face detection are employed to determine a region of interest where to extract features used by a tracking algorithm for an autonomous gaze of a PTZ camera. Finally, a face recognition phase is considered to recognize the person of interest. Results show how the integrated system is able to detect, track and recognise people inside a tough environment such as a parking lot.
