[Insight-users] Fill holes in mask

[Luis Ibanez]

Hi Radhika,

If the holes are smaller than the thinnest section
of the ON region, you can also consider  just doing
a closening mathematical morphology operation with
a structuring element whose diameter is slightly
larger than the largest hole.

This is equivalent to run a pipeline with Dilate
followed by Erode.
