Optimal (Maximum Likelihood) processing for a SAR image comprised of discrete regions of constant radar cross section is now well known. This scheme considerably improves upon windowed and iterative schemes by merging regions on an individual pixel basis. In theory, rigorous expressions for 'false alarm rate' can be defined but they are perhaps too sensitive to the underlying assumptions of independence and homogeneity. Images can be visually improved by a restraint on the 'surface tension' ofdoi:10.1049/cp:20020314 fatcat:76qmjjkcgnakfjodtq7ziowj7m
