Abstract

This paper presents an edge detection method which is well-suited to determining accurate and localized edge maps for speckled images. The maximum strength edge pruning ratio of averages (MSP-RoA) method is a ratio-based edge detector which makes effective use of edge orientation information in pruning candidate edge pixels. The method is compared to other speckle-specific edge detection methods. Test results of the MSP-RoA method for simulated speckled images and for airborne synthetic aperture radar (SAR) images are presented
