Abstract: The various technologies presented herein relate to detecting one or more
vehicle tracks in radar imagery. A CCD image can be generated from a
first SAR image and a second SAR image captured for a common scene,
wherein the second SAR image may include a vehicle track that is not
present in the first SAR image. A Radon transform (RT) process can be
applied to each pixel in the CCD image, and further, a radial derivative
(RDRT) can be determined for each pixel from RT values derived for each
pixel. Each pixel can be labelled as being related to a track, or not,
based upon a unary cost obtained from the RDRT value of that pixel,
combined with a probability of the pixel label based upon labels applied
to neighboring pixels. A labelled representation of the CCD image can be
generated based upon the determination of "track" or "not track". |
