On nonparametric edge detection in multilook SAR images
Myriam Beauchemin, Keith P. B. Thomson, Geoffrey Edwards · IEEE Transactions on Geoscience and Remote Sensing · 1998
Nonparametric alternatives based on the Wilcoxon-Mann-Whitney statistics are evaluated for edge detection in synthetic aperture radar (SAR) images. First, the power of the nonparametric test is compared to that of the ratio-of-averages detector. Then, a nonparametric change-point test is evaluated to identify the true edge position inside a fixed window.
