1. A detection and tracking method for detecting and tracking objects within a sequence of video image frames, the method comprising; detecting keypoints in a current image frame of the video image frames; assigning local appearance features to the detected keypoints; establishing Point-Motion-Pairs between the current image frame and a previous image frame of the video image frames, using the local appearance features; using the Point-Motion-Pairs to form seed coherent motion object models; and accumulating additional matches between image locations in the current image frame and the previous image frame to form complete coherent motion object models of the objects being tracked, wherein the steps are performed by at least one electronics processor.
