This thesis motivates a fully automatic approach for locating roads in aerial video by using active contours in conjunction with motion cues. Directed active contours provide ideal parametric representations of roads due to their ability to fit the variety seen in road shapes. Motion in stabilized aerial video can be represented as a distribution of spatio-temporal derivatives. These motion cues can then be incorporated into the energy function, which yields active contours that better model the active roads in a scene. We present results using this approach on typical models of both urban and rural scenes.
