[Insight-users] Topology preserving level sets

[Miller, James V (Research)]

I looked at papers relative to the implementation in ITK.  I think we could
put the appropriate processing up in SparseFieldLevelSetFilter and, via
a mode, let every LevelSet subclass utilize tolopology preservation as the
user
sees fit.

I can't remember off the top of my head where I was going to put the
new code.  But it was somewhere between CalculateChange() and ApplyUpdate().

I've implemented it for 3D only and for the 26-6 connectivity pair only 
  as a child class of the itkGeodesicActiveContourFilter.  The code is 
decidedly unclean, but has potential.  It *seems* to work.

At the moment, I have less than 0 time to work on this.  When this 
situation changes, I plan to clean up the code and contribute the class. 
If you want to play around with the code as it is now, I can send it to 
you.  Fixes and contributions are obviously greatly appreciated.
