[Insight-users] itkLinearInterpolateImageFunction

[Anja Ende]

Hello all,

I was looking at the implementation of the linear interpolation filter
in itk and found it in itkLinearInterpolateImageFunction.txx.

This class assumes that the image sampled points lie on a regular
grid, right? What about interpolation when doing non-rigid
registration? The index points generated from the registration process
would lie on an irregular grid, right? What interpolation classes
could we use then?
