Applies a minimum filter with kernel size 3x3 n times to an image iteratively.
Odd iterations are done with box neighborhood, even iterations with a diamond. Thus, with n > 2, the filter shape is an octagon. The given number of iterations makes the filter result very similar to minimum sphere. Approximately:radius = iterations - 2
