MaxFltImg
DESCRIPTION
Computes the maximum filter of an image.
A 3 x 3 neighborhood of points is sorted by value and the target point
is replaced by the maximum value. The result is similar to a
morphological dilation operation. Other rank based filters are
MedianFltImg, MinFltImg, and RankFltImg. The maximum filter is similar
to the median filter, discussed in:
