<P>PROBLEM TO BE SOLVED: To provide a tracking device capable of accurately tracking by eliminating the mutual spacial contradictions of a plurality of tracking points even if an object is formed of a non-rigid body. <P>SOLUTION: In an inputted dynamic image, the candidate destination points of the plurality of tracking points specified by a user are extracted, and corrected so that any contradiction does not occur in the mutual spacial positions of the plurality of destination candidate points, and the coordinates of the corrected candidate points are obtained. A kalman filter is applied to the coordinates thus obtained to estimate more accurate destination coordinates. Thus the deformation and movement of an area including the tracking points can be detected. <P>COPYRIGHT: (C)2004,JPO |
