Claim 22:
23. The method of claim 14, wherein assigning each of the candidate ROIs in one image frame into one of the trajectories comprises: (a) assigning the candidate ROIs to separate new trajectories when there are no active trajectories; (b) when there are active trajectories, assigning the candidate ROIs to a closest active trajectory when distances between locations of the candidate ROIs and a last ROI in the closest active trajectories is smaller than a distance threshold; or (c) when there are active trajectories, assigning the candidate ROIs to a new active trajectory when distances between locations of the candidate ROIs and a last ROI in the closest active trajectories is larger than the distance threshold.
