Image segmentation, which usually employs a statistical model, is an essential step in synthetic aperture sonar (SAS) image processing. This work addresses the Rayleigh mixture model (RMM), representing SAS underwater amplitude image. High resolution SAS image of detected artificial object is segmented using RMM and Markov random field (MRF) model. We(More)
