In this paper, we describe a real time vehicle tracking using image processing techniques. The moving vehicles are segmented from the input image sequence using differential edge images. The vehicles are tracked using statistical invariant moments. The direction of vehicles is determined by the Hough transform. The direction of the vehicles is determined from the straight lines in the direction of the principal axes of the vehicles. The motion information is calculated from the displacement of the vehicles and the change of direction of vehicles in the consecutive frames. The algorithm is tested on different real time image sequences.
