Abstract:
We present a binocular active vision system that can attend to and fixate a moving target. Our system has an open and expandable design and it forms the first steps of a long term effort towards developing an active observer using vision to interact with the environment, in particular capable of figure-ground segmentation. We also present partial real-time implementations of this system and show their performance in real-world situations together with motor control. In pursuit we particularly focus on occlusions of other, both stationary and moving, targets, and integrate three cues to obtain an overall robust behavior, ego-motion, target motion and target disparity. We argue that an active vision system must be open, expandable, and operate with whatever data are available momentarily. The integration of many cues and concurrent modules, rather than sophisticated recovery mechanisms, forms a pervading theme. We stress that an active system must be equipped with means and clues to change its attention, while it otherwise is purely reactive. This system is therefore equipped with motion detection for changing attention and pursuit for maintaining attention, both of which run
