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.-This Filter provides a selective mean (averaging) lter. In contrast to the standard
