Mean field relaxation and SAR image segmentation
E. Bratsolis, Marc Sigelle · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2004
A method for speckle reduction and segmentation of synthetic aperture radar (SAR) images is presented here. As a first step we consider a preclassification to a specific number of labels (classes). The second step (final classificatio) is the relaxation labeling process. The method can be considered as a fast unsupervised technique. We have worked in 3-look simulated and real ERS-1 amplitude images.
