Description: A long optimisation with different image resolutions in NRR. The second of the two uses coarser resolution.
Intent: prove that going to finer resolution (with up to 20x20x20 knot-points does not improve, based on very long registration.
Results: There is no apparent difference between the results, maybe only at sub-pixel level.
Conclusions: Lowering the level, i.e. increasing the resolution, does not improve registration results.
