[Insight-users] mesh creation from segmented image

[Luis Ibanez]

Hi Miladi,

Thanks for sending your example images.

Given that you already have segmentations for
each slice, the easy way to generate a contour
is to take the 3D binary image that you have
and to pass it to the filter:

http://www.itk.org/Insight/Doxygen/html/classitk_1_1BinaryMask3DMeshSource.html

This filter will produce an itkMesh that is the
contour of the segmentation.

This is interesting if you plan to do something
like Deformable Models.


Note that if your purpose is to do visualization
of the contour, then you will find more useful
to convert the ITK image of the segmentation into
a VTK image, and then pass it to the vtkContour filter.

You will find examples on how to do this in the
directory:

     InsightApplications/Auxiliary/vtk/
          itkReadITKImage3DSegmentShowVTK.cxx



     Regards,


        Luis
