Ship wakes detection in SAR images

Detecting ship wakes from spaceborne SAR images is significant. But it is particularly difficult, especially detecting-thin line features. Because those features are not only affected by speckle but also affected by various other factors and the image resolution is often coarser than the wide of the corresponding objects. In this paper, an algorithm is developed based on line-support regions of similar gradient orientation and the Radon-transform. It was found that this approach works fairly well for the images where the ship wakes are by no means distinct.
