[ITK] ITK NeighborhoodIterator alternative

[David Froger]

Hi,

I have the same question, this benchmark shows that NeighborhoodIterator 
are very slow for large 2D images: 
https://github.com/dfroger/quickstart/tree/master/itk/iterators

Did I made something wrong in using NeighborhoodIterator? Is there an efficent
alternative?

ITK was built in release mode.

Thanks,
David
