[Insight-users] ThresholdSegmentationLevelSet smoothness

[Oleksandr Dzyubak]

Dear Luis and ITK users,

I tried to use the ThresholdSegmentationLevelSet image filter
to segment an elongated gaussian cylinder. The segmentation went fine
but I still have couple questions.

1)
In the segmented cylinder, its edges are too rough with a bunch of spikes.
According to the user manual, the CurvatureScaling parameter could be used
as a smoother but it did not help much even if I vary it over a quite 
wide range [1-100].
Any suggestions on how to get the segmented object with smooth edges?
What other control parameters could be used for that?

2)
In the segmented image, the first and last slices of the cylinder are 
excluded.
It looks like propagation gets stuck at the ends.
Any suggestions on how to enforce it to process the whole object?

Thanks,

Alex
