[Insight-users] 3D volume image neighborhood iterator?

[Wang Zhimin]

Hi, all,

Thank you all in advance for reading this question.

I am looking for a way to read all the neighborhood voxels for a 3x3x3 neighboring window for a 3D volume image. 

I find all the online resource, itksoftwareguide, itk example, and mailing list archive, all failed.  

Can any one give me some example codes to do this?

Some notes:
1) I think a ImageSliceIteratorWithIndex may work, but I cannot figure out HOW through the example.
2) I want to use 2D neighborhood iterator for each slice, but I need to coordinate at least 3 slices (previous, center, and next) with correct index, and it is too complicated. 
3) I also want to use itk::NeighborhoodAlgorithm::ImageBoundaryFacesCalculator to get the non-boundary region, I don't have any boundary condition, so what I need is just to focus on the non-boundary region.

Once again, thank you.

Regards,
Zhimin
