Abstract

This paper describes a new gradient algorithm for enhancing linear features in synthetic aperture radar imagery. The algorithm is based on finding the maximum average gradient over a local window centered on a pixel. The algorithm also outputs the local direction of linear features. The algorithm attempts to compensate for decorrelation resulting from the speckle in radar imagery by considering larger pixel neighborhoods or processing windows.
