[Insight-users] Question about Conntected Regions

[Luis Ibanez]

Hi Zein,

This looks like a classical target for
mathematical morphology.

You may disconnect the two regions using
'openning' which is simply an erosion
followed by a dilation.

You will have to use a circular structuring
element with a diameter equal to the width
of the structure that you want to eliminate.

Note that as a collateral effect of the
opening, the final shape will be more rounded.
