Abstract: In this paper, an expectation-maximization (EM) approach assisted by Dempster-Shafer evidence theory for image segmentation is presented. The images obtained by synthetic aperture sonar (SAS) systems are segmented into highlight, background and shadow regions for the extraction of geometrical features. Firstly, the proposed approach chooses the likelihood function given by Sanjay-Gopal ...
