[Insight-users] What is GetNeighborhoodIndex of the ShapedNeighborhoodIterator?

[David Doria]

In something like this:

http://www.itk.org/Wiki/ITK/Examples/Iterators/ShapedNeighborhoodIterator_Manual

these lines:

 std::cout << "New position: " << iterator.GetIndex() << std::endl;

      std::cout << ci.GetNeighborhoodIndex() << " -> "
<< ci.GetNeighborhoodOffset() << " = " << ci.Get() << std::endl;

produce:

New position [8, 8]:
199 -> [0, -1] = 0
241 -> [0, 1] = 0

I understand the position (from GetIndex) and the offset (from
GetNeighborhoodOffset), but what are the values 199 and 241 that
GetNeighborhoodIndex returns for every pixel?

Thanks,

David
