[Insight-users] On the convergence speed of level set methods

[Kai Li]

Hi,
   I tried the level set method (GeodesicActiveContour) in ITK. I found
that when the front grows larger and larger, the time for each iteration
becomes slower and slower. It finally takes a long time for the whole
process to converge. This is especially the case for segmenting
shapes like the white matter. I'm investigating methods for improving this
problem. The question I'd like to ask here is whether ITK already has any
effective mechanism for this problem.

Thanks,
Kai
