| Abstract(in English) | We propose a robust object tracking method using an extended particle filter. In object tracking using a normal particle filter, we often fail tracking the object which has large or rapid motion. If we distribute the particles widely in such cases, the accuracy of tracking is decreased unfortunately. Here, we extend the prediction framework of a particle filter for tracking such a quickly or largely moving object. We first distribute some particles for reconnoitering the moving object and compute the likelihoods of the reconnaissances. We then estimate the displacement of the target from the likelihoods and distribute all the particles using the estimated displacement. If the obtained likelihoods are insufficiently, we repeat the reconnoitering cycle. This framework makes tracking be robustly and accurately. We show the effectiveness of our method by the real image examples. |
