DESCRIPTIONComputes 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:
