Hi Josh,
I'm following your and Luis's suggestions but from what I can see all of the level-set examples require an initial estimate of the surface you are trying to detect. Do you know of any methods that would not need an estimate of the surface in the entire volume beforehand? It would be kind of useless for the application I'm trying to implement if I'd have to get an initial guess beforehand.
Thanks,
Steve

Hi Steve,
Have a look at the level-sets chapter the Software Guide and the
NarrowBandCurvesLevelSetImageFilterTest in
Testing/Code/Algorithms. These should help.
