Abstract :
A method for detecting man-made features in synthetic aperture radar (SAR) imagery is described. The method is based on matching the local histogram against a family of Weibull densities. The Weibull density is defined by two parameters, the median and the skewness (Weibull parameter). Regions containing man-made objects have Weibull parameter values that are smaller than those containing natural features. In experiments performed with aircraft SAR imagery, man-made features are effectively discriminated from natural features using this method
