Frame-based tracing of multiple objects

In tracking feature points, aside from the matching problem, tracing many objects that are coming and going out of the scene is still another problem. A frame-based tracing algorithm to mark and follow the matched object is presented. Experimental results showed that the algorithm is able to successfully track multiple objects simultaneously, including entering, exiting, and continuing events. The algorithm was useful when there are many objects that enter and go out of the scene during the video taking.
