METHOD OF FILTER SELECTION FOR SPECLE-NOISE SMOOTHING IN SAR IMAGES
Abstract
A method for comparison of different SAR image filtration techniques is presented. It allows selecting the filters with better speckle noise smoothing effect. Unlike the known approaches, the presented method is based on ENL parameter calculation for automatically selected areas.
