[Insight-users] Region extraction from watershed segmentation output

[Sébastien Wilfart]

Hi!

I would like to extract a specific region from the ouput of a watershed
segmentation. The output of the segmentation filter is a labeled image where
each pixel is assigned an unsigned long integer label that groups it within
a connected region.

1) Is it possible to get the label corresponding to a specific region (for
example, by specifiying a pixel belonging to the region of interest) ?

2) Is it possible to extract the surface corresponding to a specific region
(for example, by specifying the region's label) ?

Thanks for your help
