抄録(英) This paper first utilizes generalized Gamma model to fit the statistical characteristics of co-registered SAR images. Then, extract the difference map through measuring the similarity between PDFs by Kullback-Leibler Divergence. Afterwards, apply a combination of KS & KL test to evaluate and choose fitting function of the difference map for the model-based KI threshold segmentation automatically. Experiment was carried on the multi temporal SAR images for Olympic Village of Beijing, acquired by TerraSAR-X and Radarsat-2, as well as Shunyi District of Beijing, acquired by Envisat-ASAR. Such results confirmed the proposed method is more sensitive in detecting regions that have no variance in mean value, but differ in texture, than traditional methods
