Regions Segmentation from SAR Images
In this paper, we propose an approach based on the level set method for segmenting SAR (Synthetic Aperture Radar) images. In particular, the segmentation process presented consists in the evolution of an initial curve, including the interested region, until it reaches the boundary of the area to be extracted. The procedure proposed allows to obtain the same result of segmentation independently of the initial position of the curve. The results are shown on both synthetic and real images. The analyzed images are SAR PRI (Precise Images), acquired during the mission ERS2.
