CRV 2014 - the conference on computer and robot vision location:Montréal, Québec, Canada date:7-9 May 2014
Nowadays, many lectures and presentations are recorded and broadcasted for teleteaching applications. When no human camera crew is present, the most obvious choice is for static cameras. In order to enhance the viewing experience, more advanced systems automatically track and steer the camera towards the lecturer. In this paper we propose an even more advanced system that tracks the lecturer while taking cinematographic rules into account. On top of that, the lecturer can be filmed in different types of shots. Our system is able to detect and track the position of the lecturer, even with non-static backgrounds and in difficult illumination. We developed an action axis determination system, needed to apply cinematographic rules and to steer the Pan-Tilt-Zoom (PTZ) camera towards the lecturer.
