Abstract
A new linear feature detector for synthetic aperture radar (SAR) images is presented in this article by embedding a
three-region filter into the wedgelet analysis framework. One of its main features is that it can detect linear features
with a range of varying widths and orientations in the same image by changing the direction and size of the detector
mask within a multiscale framework. In addition, this detector takes into account both statistical and geometrical
characteristics to detect line segments directly instead of detecting target pixels. To show its effectiveness, the
detector is applied to extract one of the most important linear features: roads. Results and comparisons with several
multiscale analysis techniques as well as ratio correlation detector on DLR E-SAR images reveal its advantages.
