This Filter provides a selective mean (averaging) lter. In contrast to the standard mean lter,it preserves edges better and is less sensitive to outliers(outliers are those that are not included in the measurement taking place.In this case averaging). The lter smooths an image by taking an average over the neighbouring pixels, but only includes those pixels that have a value not deviating from the current pixel by more than a given range. The range is dened by the standard deviation of the pixel values within the neighbourhood . If the number of pixels in this range is too low (less than `Minimum Pixel Fraction ), averaging over all neighbouring pixels is performed.With the `Outlier Aware option, averaging over all neighbouring pixels excludes the center pixel.
