[Insight-users] [vtkusers] how to pass vtkimagedata to ITK

[Luis Ibanez]

Hi Ali,

Please look at this Insight Journal paper:

"Seamless VTK-ITK pipeline connection for image data handling"

http://www.insight-journal.org/browse/publication/146
http://hdl.handle.net/1926/495

The source code is available at

         InsightApplications/vtk/

                          vtkKWImage.h
                          vtkKWImage.cxx
                          vtkKWImageIO.h
                          vtkKWImageIO.cxx


BTW: You could have done the same process using
ITK components:

                     1) Reading DICOM
                     2) Shrinking the image
                     3) Thresholding the image

You will find instructions on how to do each one
of these things in the ITK Software Guide

        http://www.itk.org/ItkSoftwareGuide.pdf


You may find useful however, to use VTK for displaying
the results of your segmentation and for interacting with
that display.

For example as illustrated in

InsightApplications/Auxiliary/vtk
           itkReadITKImage3DExtractContourVTK.cxx
           itkReadITKImage3DSegmentShowVTK.cxx
           itkReadITKImageSegmentShowVTK.cxx
           itkReadITKImageShowSplineVTK.cxx
           itkReadITKImageShowVTK.cxx




    Regards,


          Luis
