[Insight-users] Troubles with the manipulation of label objects

[Cagatay Bilgin]

Antonio, when you add two binary images (lets say 0 background 1
foreground), you are getting a value of 2 when both of the inputs are 1 at
that specific location. addImageFilterPointer_2's output is most likely not
binary, which explains the issue you are observing.
