In this paper a new promising method of speckle ltering is described and applied to both, synthetically generated and real SARimages. The new method, which w e call EPOS Edge Preserving Optimized Speckle-lter, is based upon the statistical properties of speckle noise. The knowledge of speckle variance allows the distinction of homogeneous areas from those, containing edges or single scattering targets. This discrimination method is used within a variable sized lter matrix to choose a region,doi:10.1109/igarss.1994.399674 fatcat:6fqx2jrwljfvnauwxabdkotdhq
