A ball of radius 1 would not cover the 8 corners of a 3x3x3. The
structuring element is just a Neighborhood. You could just create a
neighborhood of radius 1 and Fill() it with ones.

Subject: [Insight-users] BinaryBallStructuring element
Hi Luis,
I have some questions regarding the BinaryBallStructuring element.
If I set the radius to 1, it is not 3x3x3 with all ones. Instead the outer
most pixels (8 of them) are set to 0. I was not sure if this is the standard
way of defining a ball structuring element because this is more like a cross
to me. Or am I misinterpreting it? Is there a structuring element available
where all 3x3x3 are set to 1?
Thanks
Radhika
