Observing motion by multiple visual tracking agents

This paper describes a method to observe a moving object with multiple visual tracking agents. When a robot vision watches an object, it employs several tracking agents to monitor key features of the object. Each tracking agent is controlled by its visual feedback. In order to perform robust tracking, the authors introduce constraint control between agents. This method is effective in observing a motion of not only a single solid object but also a structured object such as a human hand. Several examples applied to 3D motion are shown
