[Insight-users] Watershed segmentation -- how to access the detailed results?

[Atwood, Robert C]

Once an image has been processed by the watershed filter, is there
already a list of the regions and how many voxels are in each one? or
even which regions neigbour upon which other regions? It seems that this
information must be generated at some point during the watershed filter
.. If so, how can this list be accessed?=20

(Instead of iterating through the resulting image array and counting ,
and locating adjoining regions, etc.)

Thanks,
Robert
