Synthetic Aperture Radar (SAR) images are inherently affected by speckle noise which is due to the coherent nature of the scattering phenomena. Even though speckle carries itself information about the illuminated area, it degrades the appearance of images and affects the performance of scene analysis tasks carried out by computer programs (e.g., segmentation and classification) or even by human interpreters. To counter this problem, users resort often to the multilook technique, which amounts to incoherently averaging a certain number (defined by the number of looks) of independent images, thus reducing noise intensity, but often at the cost of a clear loss in image resolution. Therefore, it is certainly preferable to develop suitable filtering techniques, which reduce noise significantly but, at the same time, preserve all the relevant scene features, such as radiometric and textural information.
