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