Dear Stephen,
at the moment we are putting things together so that the software can be
configured and deployed more easily (GUIs, documentation and such).
Until the end of September we want to have a binary distribution ready
that ships a pre-configured Apache Felix with all the bundles already
installed.
As hardware we use currently a somewhat older (approx. 2 years) Dell
Optiplex desktop machine with an NVIDIA GT 220 GPU. As overview camera
we have tried Logitech C910 and C920 as well as Facevision TouchCam N1,
all perform very good. The PTZ camera we work with at the moment is a
Sony EVI D70P and we will be testing the system also with an EVI D100 in
the lecture hall.
Cheers,
Benjamin

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?
Regards
Stephen

Dear All
ELAN e.V. together with Osnabruck University and ETH Zurich would like to announce they
are working towards an automated camera tracking system "LectureSight", fully
integrated with Opencast Matterhorn.
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.
Regards
Rüdiger, Olaf A.
