摘要：Image segmentation has the general goal to define regions within an image, in which all pixels have similiar properties. For fully- polarimetric SAR data this is often done by spectral classification without any use of spatial information. On the contrary the proposed method aims to find homogenous segments in the image, which should be compact and connected if possible. A multiresolution image pyramid allows to calculate information based on regions of different size instead of single pixels or small neighbourhoods. Furthermore, a relaxation approach is used to defer the segmentation decisions until more accurate information is available
