EXAMPLE

Remove the multiplicative noise from a subarea of the radar image GATINEAU.PIX. In order to find noise variance, the program HIS is run on a window of a flat area. The square of the statistical standard deviation of the grey levels in this area is the variance noise (NOISEVAR=388). The user can also determine the noise variance for multiplicative noise image if the number of looks of the image is known. Filter size is 7x7 and multiplicative noise mean is 1.
