Calculation times CC
(old data, so absolute timing obsolete...)
Calculation time is direct proportional to # voxels times # kernel directions:
Example: # voxels=128x128x128 (appr. 2

), # directions=106

The calculations for the parallel transport lines used in the CC
approach are extremely suitable for implementation on parallel
hardware!
