                         removal, five filters with characteristics of robustness, suitable 
                         for speckle noise reduction, are derived and implemented. These 
                         filters are the ones based on the trimmed maximum likelihood and 
                         moments estimators, the ones based on the median, on the 
                         inter-quartile range and on the median absolute deviation. 
                         Assuming that observations within a synthetic aperture radar image 
                         are outcomes of independent Rayleigh random variables, these 
                         filters exhibit a good performance from both the signal-to-noise 
                         reduction and from the edge preserving criteria. The problem of 
                         filtering in an image is posed as an estimation problem.",
