Thanks very much, Luis,
I've now got a nice-looking inverse deformation field, but I am having
trouble quantifying (extracting vector-field data) that matches my
qualitative observations.
Once I get the deformation field from the Demons registration, I can use
WarpImageFilter, with my 'moving' image data, and obtain a 'fixed' image
look-a-like. Great! I would like to quantitatively report the
transformation that takes the 'moving' image -> 'fixed' image, and I
believe I need the inverse transform to do that (can you confirm?)
I then am opening the *inverted* deformation field in Paraview and
exporting the vector values at each pixel (this data is used for a
validation method I have).
Does all of that seem straightforward? My qualitative data (the output of
the 'registered' image set looks really great!) and my quantitative
visualization of the deformation field in paraview do not seem to line up
as nicely as I had hoped.. could this simply be a result of the Demons reg.
and inverting a def-dield?
If the 'registered' output from the Demons routine looks VERY MUCH like my
'fixed' data set, can I not safely assume that the deformable registration
was a success?
Thanks again for your help,
