[Insight-users] Re: vtkview and files converted by ITK

[Luis Ibanez]

Hi Paul,


I'm affraid that you will require the assistance of the
team that developed vtkview at (www.imageregistration.com).
As you probably know, this project is unrelated to ITK.


If you want to perform registration with ITK code you can
look at the examples on rigid registration illustrated in
the ITK Software Guide.

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


All the source code for those examples is available under

              Insight/Examples/Registration


For Rigid Registration of 2D images you may want to take
a close look to the example:

        Insight/Examples/Registration/
                     ImageRegistration5.cxx

This example is described in detail in the ITK Software Guide
in Section 8.5.1, "Rigid Registration in 2D", pdf-pages 263-272.

You run this example by simply providing in the command line
the filenames of the two images to be registeres, and the
filename to be used for saving the resampled registered image.



Please let us know if you have any further questions,


     Thanks


       Luis
