Modern aerial imaging platforms provide wide-area motion imagery (WAMI) at high spatial and moderate temporal resolutions making feasible a range of new applications. We consider the dual tasks of registering WAMI frames to geo-referenced vector road-maps and tracking vehicles through the progression of WAMI frames. We present a novel algorithm that(More)
For specular regions (SRs), the assumption of brightness (or other) constancy between images corresponding to multiple views of a scene breaks down. As a consequence, optical-flow (OF) based motion-estimation (ME) algorithms that rely on constancy assumptions fail for specular regions. At the same time estimation of SRs in an image is also prone to errors,(More)
