German Aerospace Center (DLR)
I'm a researcher at the German Aerospace Center (DLR). The DLR is Germany's national research center for aeronautics and space. The DLR has approximately 5.600 employees and 13 locations in Berlin, Bonn, Braunschweig, Bremen, Cologne (headquarters), Goettingen, Hamburg, Lampoldshausen, Neustrelitz, Oberpfaffenhofen, Stuttgart, Trauen and Weilheim. I'm currently located in Braunschweig at the Institute of Flight Guidance and working in the field of Unmanned Aerial Vehicles (UAV) integration into controlled airspace.
Dynamic Scene Description and Atypical Event Detection
My doctoral thesis is about the automatic detection of atypical changes and events in dynamic multi-object scenes. Examples for such scenes are streets, parks, train stations, public places, airports, sports fields, highways, shopping malls etc. The actors or objects traveling through such scenes are pedestrians, bicycles, cars, boats, airplanes, sportsmen or customers. Information on the observable states of the actors or objects is made available by sensors.
Based on object state vectors, a new approach is proposed for a map-based representation of the scene dynamics. Two methods are introduced, map-based change detection (MBCD) for the detection of overall scene changes and map-based trajectory analysis (MBTA) for the evaluation of individual object trajectories. Both methods work with real-life multi-object scenes without signatures or training. They were implemented with three different scenes and each scene was annotated by ten human participants in a separate experiment. The evaluation of the results shows the strengths and limits of the new approach and suggestions are made where to continue with further work.
The thesis is out in print and may be available in your local library. See the publications page for details.
