Unsupervised Bayesian Classification Of Sar - Images
Hans-Christoph Quelle, J.-M. Boucher, Wojciech Pieczynski · 2005
We present a non-supervised method of bayesian contextual radar image segmentation. We adopt the hierarchical image model (HIM) from Kelly and Derin. In contrast to their global segmentation method a local method is used in order to speed up the segmentation..The algorithm for parameter estimation is 5EM, a recem variation of EM. The algorithm obtained is tested on synthetic images and also applied to the segmentation of real SEASAT-scenes.
