Effective method for follow-up tracking

We explain our effective method around what we consider as the three crucial problems in follow-up tracking; in this abstract, we just sketch an outline of our explanation. The first crucial problem is the establishment of two index tables through discretization of motion of camera: (1) rotation index table for pan motion (or rotation in the horizontal plane) and for tilt motion (or rotation in the vertical plane); (2) background index table. The second crucial problem is, with the camera fixed in position, the real-time detection and tracking of moving targets; the tracking is done by a specially designed Kalman filter; particular attention is paid to solving the occlusion problem. The third crucial problem is the scheduling of the pan and tilt motions of camera. Experimental results show that our method is robust and effective in follow-up tracking of interested target with complex background, and can extract moving targets real-time.
