Abstract :
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 the segmentation results or the computational cost.
