Robust object tracking in a dual camera sensor

In this paper, a cooperative system for target tracking for Omnidome is presented. Omnidome is a dual-camera sensor composed of an omnidirectional camera and a Pan-Tilt-Zoom (PTZ) unit. The tracking system is based on color histogram analysis, and is triggered by a motion detector; it has been designed in order to get the best performance when performing people tracking. The system is capable of extracting information from one video source, and exploit it in the analysis of the other. This capability turns out to be particularly useful when a target tracking is started in the image provided by the PTZ camera, exploiting the information already gathered by analyzing the omnidirectional image.
