                         to extract local statistical properties of images in order to 
                         improve a speckle noise 'Maximum a Posteriori' (MAP) filtering 
                         performance. The strategy consists in growing the local 
                         statistically homogeneous area near the pixel in order to estimate 
                         its MAP filtering parameters. Measures evaluating both the

                         are computed. The use of region growing is investigated as a 
                         promising approach compared to a fixed size and shape
