.... described here is not restricted to curves; it could also be applied to real time trackers based on polygons or other geometrical representations [27, 17, 20] Some tracking applications, surveillance for instance, call for a panoramic field of view which can be achieved by a pan tilt head [9, 26, 25, 7]. Such a head is used in the experiments reported here. yThe first author now works for Canon Research Europe Limited, Surrey Research Park, Guildford, UK, GU2 5YF A major problem in achieving robust object tracking is the distracting effect of background objects clutter. Strong features in ....

.... systems from research conducted using purely static vision systems, the term active vision was introduced [Ballard Brown(1993) Although most of these approaches are inspired by biology s active vision [Ferrell(1996) Takanishi et al. 1995) Capurro et al. 1996) Berthouze et al. 1996a) Murray et al. 1992), only few implementations of oculomotor systems can be found that try to emphasize biological plausibility. In this paper, we will focus on an active vision system that employs as much as possible computational mechanisms that have been discovered in neurophysiological research on primates. ....

In theory, TPM can provide both the quickest and the smoothest possible state to state motion given ....

....camera platforms. It is with this concept in mind that we have modeled our design as a single eye with independent pan and tilt. Although this configuration suffers from the need to ensure that the tilt movement is precisely matched between cameras in a standard vertically aligned stereo setup [ Murray et al. 1993 ] this disadvantage is sufficiently correctable within the control strategy and it was felt that the difficulty was outweighed by the flexibility and reusability offered in the modular design. 4.

KINEMATICS: SPECIFICATION IMPLEMENTATION Two practical kinematic designs are available, as sketched in Fig. 3 (from [12]) i) Helmholtz (or common elevation) in which both cameras tilt up and down and verge independently about axes perpendicular to the elevation plane; and (ii) Fick (or gun turret) where each camera verges around an axis which remains vertical, and elevates about an independent horizontal axis. ....

....which visual feedback to utilize, and the servo controller which uses that feedback to control the mechanical plant. In this paper we explore the implementation of the visual processing and gaze control strategies required for real time surveillance on Yorick, our reactive head eye platform [1, 2, 3]. We demonstrate that straightforward visual processes and a straightforward gaze control strategy, when run on integrated active vision mechatronics, can create a system capable of functioning over extended periods. We show too that the interaction of control and vision is crucial; it is the gaze ....
