[Insight-users] InterpolateImageFunction neighborhood

[Julien Michel]

Dear ITK users,

We are trying to extend the itk::ResampleImageFilter so as to make it 
streamable for large images processing. For the moment we only consider 
affine transforms. What we do is to transform the requested region 
corners, and then to take the bounding box of the transformed corners.

Unfortunately, this is not sufficient since most of the interpolators 
work with a neighborhood. So we need to know for a given interpolator 
what is the requested neighborhood in order to pad our requested region.

Is there a generic method in the InterpolateImageFunction to get this 
neighborhood information ?

Thanks a lot for your help,

Julien
