      Either `size` or `footprint` must be defined. `size` gives
      the shape that is taken from the input array, at every element
      position, to define the input to the filter function.
      `footprint` is a boolean array that specifies (implicitly) a
      shape, but also which of the elements within this shape will get
      passed to the filter function. Thus ``size=(n,m)`` is equivalent
      to ``footprint=np.ones((n,m))``.  We adjust `size` to the number
      of dimensions of the input array, so that, if the input array is
      shape (10,10,10), and `size` is 2, then the actual size used is
