Hi Olaf and team, This prototype looks great! We are very interested in trying this out in some venues when it's available.
Could you share the details of the actual cameras and capture devices being used?

The module will provide a solution to automatically track speakers in a classroom situation, thus providing a more convenient shot of the instructor when compared to a fixed overview camera. The goal is to come to a subjective quality close to a manned camera in a standard setting, thus reducing the staffing cost for lecture recording significantly. Technically , the software consists of a set of OSGI bundles that can be added to an existing Matterhorn system or live as a stand-alone application. The video analysis portions of the system utilize the GPU through the OpenCL standard. The software breaks down into six major components: 1. a scene analysis that discovers and tracks the positions of moving objects in the scene 2. a plug-in mechanism for object analysis modules 3. a facility for communicating with PTZ cameras (currently supports Sony VISCA protocol) 4. a module that controls the movement of the PTZ camera 5. a virtual camera operator that executes camera control strategies defined in JavaScript 6. a GUI for tuning the system for individual class rooms The project is based on a bachelor thesis by Benjamin Wulff (described at http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=6123405&abstractAccess=no&userType=inst with the original project name "OpenTrack") and has Benjamin leading this effort with contributions from Alexander Fecke. LectureSight will be piloted in situ at UOS and ETH in the fall semester 2012. Expect to be informed about first results by the end of the year. For a sneak preview, take a look at the current development snapshot (http://video2.virtuos.uni-osnabrueck.de:8080/engage/ui/watch.html?id=6dba66d9-0a53-45ed-bc67-7ab3bf50b31c) or go to the project website http://lecturesight.org/. Feedback and questions are welcome.
