Description: Given the observation that refined resolution is not very necessary, a large number of knot-points (up to 50x50x50) is being considered. Experiment 1 is longer than 2.
Intent: Showing that many knot-points at coarse resolution lead to good results.
Results: Good registration that continues to improve slightly at the later stages.
Conclusions: A large number of knot-point required a great deal of time for little (yet prevalent) improvements.
