[Insight-developers] itkVectorNearestNeighborInterpolateImageFunction

[Bill Lorensen]

Karthik,

While trying to track down a failing test, I noticed that the output of 
ResampleImageFIlter9Test looked strange. It uses the subject image function 
to do nearest neighbor interpolation of an RGB image. A pattern of zero 
pixels is noticeable in the baseline test image. Upon further 
investigation, I looked at the code in the subject filter. I'm not sure why 
it is so complicated. Why doesn't it use the same logic as 
itkNearNeighborInterpolateImageFunction. If I drop that code into the 
Vector code, the resulting image looks appropriate.
Any ideas?

Bill
