How can I do this? I've read something about the "itkLableMaskImageFilter" and "itkLabelMapToBinaryImageFilter", but cannot figure out how to use them.

I have put many examples of LabelMap operations here:

You may be interested in how to:

Iteratively process each label:

Remove labels based on shape properties:

I just added this one:

which I believe is exactly what you're looking to do here.

Good luck,
