Abstract: The method and apparatus for providing motion control signals between a fixed lens static camera and a PTZ camera that includes an adjustable-in-use focal length adapted to provide improved surveillance. In one aspect of the present invention, the improved method and apparatus includes an improved PTZ process in which fuzzy logic based information is utilized to achieve a set of more reliable P/T/Z parameters. In another aspect of the invention, the fixed lens static camera and the PTZ camera are mounted vertically on top of each other. In another aspect of the present invention, there is provided an automatic self-calibration between the fixed lens static camera and the PTZ camera. In another aspect of the present invention, there is provided a cost-effective standalone single board DSP solution.

Abstract: The present invention relates to a method and apparatus for adaptive mean shift tracking. In one aspect of the invention, there is provided a method that allows the tracking of an object, with an associated target model, through successive frames of a sequence using a mean shift kernel that has an adjustable scale, and the adjustable scale is automatically updated. In another aspect, the invention the target model is updated as the object continues to move in successive frames. In yet another aspect of the invention, the step of automatically updating further refines the estimate of the new spatial location of the object within the successive frame, and in one particular implementation, the new spatial location is determined by maximizing Bhattacharyya coefficients.
