Automated Surveillance Systems of Smart Cameras in Trains.

Last year's we can observe an enormous grow of surveillance systems in the public domain. In many countries surveillance systems are under discussion because of the privacy aspects of people. In the nineties many multimodal systems were developed for surveillance in Dutch trains. The use of camera systems was complicated because of bad lighting conditions, occlusion and posture. Only recently it is possible to use smart cameras to localize and track faces and displayed facial expressions by smart cameras installed in the public domain. Most systems are based on the Active Appearance model. In this paper we present a real version of a surveillance systems called Image Processing System developed in the vision lab of TUDelft. In an experiment we recorded the behavior of stand-up comedians in trains acting in several scenarios. The facial expressions in the video footage were analyzed.
