Camerawork for intelligent video production - capturing desktop manipulations

In this paper, we introduce an intelligent system for video recording. First, we categorized targets and purposes of shooting, and discuss the cameraworks appropriate for them. Then, we propose camera control algorithms to realize such cameraworks. Based on this idea, we built a prototype pan-tilt camera control system, in which multiple cameras with different purposes automatically track and shoot the targets. We evaluated our system through recording of some presentations on desktop manipulation. The effectiveness of our algorithm was verified through some experiments.
