[Insight-developers] CurvesLevelSetImageFilter not tested properly

[Luca Antiga]

Hi all,
  while looking into itkCurvesLevelSetImageFilterTest, I noticed that  
the test is only run in 2D.

CurvesLevelSet is similar to GeodesicLevelSet except that it relies  
on minimal curvature instead of mean curvature.
Computation of the various types of curvature is performed in  
itk::LevelSetFunction::ComputeCurvatureTerm.

Looking at that method, I noticed that minimal curvature is only  
computed when dimension is != 2.
For 2D, it falls back to mean curvature.

In other words, itkCurvesLevelSetImageFilterTest does not test  
minimal curvature at all.
I just filed a bug for this issue.
The solution is to convert the test to 3D.
