[Insight-users] Segmentation of 3D object with Level sets

[Arnaud Gelas]

Ryma,

The level sets framework may help you in this task.

However, the choice of the "terms" to be used and / or "functional" to 
be minimized depends on your image.
It is really difficult to tell you which method would work for your 
image with this little information and without the images.

First, I would recommend you having a look at the examples based on ITKv3:

     Examples/Segmentation/GeodesicActiveContourImageFilter.cxx
     Examples/Segmentation/ThresholdSegmentationLevelSetImageFilter.cxx
     Examples/Segmentation/LaplacianSegmentationLevelSetImageFilter.cxx

and

     
Modules/Segmentation/LevelSetsv4Visualization/test/vtkVisualize2DCellsLevelSetTest.cxx

You can run these tests and examples from your build directory if you 
have enabled BUILD_EXAMPLES and BUILD_TESTING by running

     ctest -R ${TheNameOfTheExample|Test}

Best,
Arnaud
