Automated segmentation routines may be used to extract scattering features in synthetic aperture radar (SAR) images. The watershed transform segments real-valued images into regions associated with a local minima. Watershed algorithms suffer from over-segmentation which, for SAR image segmentation, results in many more regions than scatterers. We consider an algorithm called Peak Region Segmentation...
Several SAR image segmentation algorithms, also known as extended target detection algorithms are studied and the results are compared. The schemata obtained are evaluated using criteria based on the similarity with visual segmentation of the image, and the computational resources used in the process. Finally, based in the algorithms studied some supplementary techniques are proposed in order to improve...
