[Insight-users] itk::offset gives zero for inside of objects in distance maps.

[Satyananda Kashyap]

Hi
I am trying to use the Danielsson distance map to test a sphere phantom in
3D. I have two concentric spheres. I create the distance map from boundary
of the outer sphere. I was to see the offset values at the positions of the
inner sphere border. I observe that the distances are correct but the
offset is always zero.

But when I create a distance map from the border of the inside sphere and
test for offset on the border of the outer sphere it works fine.

Can someone please comment on if it is a bug or if there is something I am
doing wrong ?


Regards,
Kashyap
