Abstract:

Recently, a great number of interests have been attracted to image segmentation methods based on the active contour model (ACM). The classical ACM and synthetic aperture radar (SAR) image segmentation methods based on the ACM are reviewed. Firstly, classical ACMs and mathematical principles of them are introduced, and the defects are analyzed when they are applied to SAR image segmentation. Secondly, classified discussion and analysis of SAR image segmentation methods based on the ACM are given. Finally, several future research directions for SAR image segmentations based on the ACM are discussed.
