Speckle in radar images has the characteristic of a multiplicative noise. In this article, two unsupewised methods are introduced to estimate the speckle noise statistics using the mean and the standard deviation of small image blocks (4 x 4, or 6 x 6 pixels). Since most radar images contain many sm
