A novel approach to resolving ambiguous situations in object tracking in video streams is presented. The proposed method combines standard tracking technique employing Kalman filters with global feature matching method. Object detection is performed using a background subtraction algorithm, then Kalman filters are used for object tracking. At the same time, SURF key points are detected only in image sections identified as moving objects and stored in trackers. Descriptors of these key points are used for object matching in case of tracking conflicts, for identification of the current position of each tracked object. Results of experiments indicate that the proposed method is useful in resolving conflict situations in object tracking, such as overlapping or splitting objects.
