[Insight-users] Neighborhooditerator walking region

[Jonatan Snyders]

Hello,

I am using a few iterators over different images but all images have
identical physical coordinates (which I checked). One of the iterators is a
neighborhooditerator. When initializing the iterators, I handed them the
same regions. But when I check their physical coordinates to make sure that
at each iteration they are at exactly the same point in space, the
neighboorhooditerator different coordinates. I did this with
TransformIndexToPhysicalPoint and GetIndex which should give the index of
the central position of the neighborhood.

I checked the ItkSoftwareGuide to see if the neighborhooditerator walks a
different path, or maybe steps out of the image near borders, but this does
not seem to be the case.

Does anyone have any idea?

Thanks,
Jon
