[Insight-users] remain pixel value after segment of ITK

[Luis Ibanez]

Hi Kidwei,

You may want to use the MaskImageFilter:
http://www.itk.org/Insight/Doxygen/html/classitk_1_1MaskImageFilter.html

Feed into it the original image and the segmented image.

You will get as output the values of the input image, but
only on the pixels that are ON in the segmented image.


However, I don't see why your "reconstruction" needs the original pixel 
values. In VTK you could simply run the vtkContourFilter on the binary
segmented image.


See for example:

     InsightApplications/Auxiliary/vtk/
          itkReadITKImage3DSegmentShowVTK.cxx



    Regards,


        Luis
