The ever increasing number of cameras in surveillance system requires automatic video analysis in order to spot critical situations and to alert the monitoring personnel in a timely manner. While most current approaches in this area aim for detecting a large number of specific events on a large set of complex application scenarios, the goal of this project is to go far beyond state of the art by developing novel online learning methods to detect unusual situations in a camera specific scenario. We will exploit the huge amount of data available for a specific camera to reliably learn usual and unusual situations.
In particular the OUTLIER project will carry out basic research in the following areas:
These generic learning algorithms will be applied for the detection of unusual situations in public places and traffic scenarios. Examples are the detection of unusual crowd behavior (upcoming panic, barred emergency exits, or toppled persons), suspicious behavior of pedestrians (e.g. going from one car to another, loitering), vehicles or persons moving on unusual locations, the detection of unusual types of moving objects and detection of unusual situations like accidents, clashes and collisions. Unlike other approaches we do not want to model these situations explicitly and individually, but we will resort to learning to discriminate the usual situation from the unusual one.
Research partners in the project are JRS, TUG for basic and applied research and Siemens for industrial exploitation of project results.
