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 mapbased
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 multiobject
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.
