[Insight-users] Visualization of Deformable Deformation Fields

First off, I have a general question about the deformation field generated
from a deformable registration process in ITK: What is contained in the
output file, and how does a software like ParaView use that file to produce
a vector-based image using the equation:
iHat*ImageFile_0 + jHat*ImageFile_1 + kHat*ImageFile_2
So I guess, to put it in different words, what do the different components
of the above equation mean?
In terms of the specific question I have regarding visualization of
deformation fields in ParaView:
1) How come the deformation field output produced from ITK's deformable
registration algorithms came out upside-down for me when viewed using
ParaView? That is, the image is flipped vertically/mirrored along the
2) How come the deformation field resulting from, say, the Demons 1
registration algorithm came out so scattered and non-uniform for me, unlike
the deformation field produced by the FEM-based algorithm?
Please note that I've made no modifications to any of the ITK algorithms
Thank you very much,
