During the satellite SAR (Synthetic Aperture Radar) data analysis it is highly important to remove all the noise components from the image. The most critical disturbance that affects radar images is speckle noise. Many different filtration methods to reduce this noise have been proposed in the literature up to now. This paper presents the results of SAR image filtration using the methods of mathematical morphology. During this work over 20 different morphological filters have been tested ? both classical ones (ope...
