Assessing Control Modalities Designed for Pan-Tilt Surveillance Cameras

Many modern video surveillance systems encompass pan-tilt cameras due to the flexibility they provide in selecting the fields-of-view, as compared to using just fixed cameras. Although patent the great potential of using the pan-tilt cameras, one has to design pan and tilt controllers whose effectiveness directly impacts on the surveillance performance. In this work we propose a metric tuned to assess the effectiveness of such control designs, and show the theoretical estimation of the metric for the case of a oneobject random-search controlling modality.
