[Insight-users] vertebrae segmentation with GeodesicActiveContourShapePriorLevelSetFilter

[Paul]

Hello mailinglist,

I' m using the GeodesicActiveContourShapePriorLevelSetFilter to segment 
2D ct data of vertebrae. I can't find the right parameters to get a good 
segmentation of the typical vertebra shape. Do you think, it is possible 
to get a good segmentation of vertebrae with the 
GeodesicActiveContourShapePriorLevelSetFilter? The following links show 
some segmentation results, the input image and the mean shape image I'm 
using. Maybe you can give me some advice how I have to change the 
parameters. I tried some parameter combinations but did not get one 
satisfying result.

mean shape image:

segmentation result with seed points: 3 propagation=2 advection=3 
curvature=1 shape=0.5 distance=5
