Abstract: Because of the filtering effect of the Markov random fields (MRF) region label model, detail structures may be preserved partially or lost entirely for synthetic aperture radar (SAR) image. The hidden MRF (HMRF) image segmentation approach with adaptive neighborhood systems based on scattering descriptor is proposed to better preserve detail features and border areas and to improve the segmentation effect. In order to improve the reliability and the adaptivity, fuzzy c-means (FCM) clustering algorithm is incorporated into scattering transform, where the choice of neighborhood shapes can be implemented adaptively. From among the different shape alternatives, the one with the highest fuzzy membership is chosen to compute the HMRF region label process. Experiment results demonstrate that the proposed algorithm improves the segmentation effect over the conventional HMRF using fixed shapes of neighborhood systems while detail structures are preserved well.
