[ITK-users] Binary Fill hole Image Filter for 3D Image

[Dženan Zukić]

Hi Abdelkhalek,

your image does not have any holes! The input and output images are binary
identical (examined using file compare tool). If I modify your input image
to also contain a real hole (not connected to image edge or the
background), it gets filled properly. See attached.

Regards,
Dženan
