                         SAR imagery, based on WM, OWA and WOWA families of aggregation 
                         operators. The values in the weight vector associated to a WM 
                         filter correspond to the same positions in the input, whereas 
                         those in OWA filters consider the ordered positions of the input. 
                         WOWA operators make use of both vectors to weight an input data 
                         vector. Here we use Genetic Algorithms to learn the weight vectors 
                         for OWA, WM and WOWA filters and assess their use in reducing 
                         speckle in SAR imagery. We present an application using simulated 
                         images derived from a real-world scene and compare our results 
                         with those issued by a set of filters from the literature.",
