SPECKLE NOISE REDUCTION IN SAR IMAGES USING INFORMATION THEORY
<p>In this work, a new nonlocal means filter for single-look speckled data using the Shannon and Rényi entropies is proposed. The measure of similarity between a central window and patches of the image is based on a statistical test for comparing if two samples have the same entropy and hence...
