[Insight-users] how can I generate the deformaion graph in ITK?

[Luis Ibanez]

Hi Guorong,

.rar is an unusual compression format. Please when sending
images use more common formats such as JPEG, PNG or TIFF.

In any case,
If you want to produce a deformed grid illustrating the
deformation field, you can simply create an image with a
rectilinear grid. Then deform it by resampling with the
WarpImageFilter:

http://www.itk.org/Insight/Doxygen/html/classitk_1_1WarpImageFilter.html

You will find examples on the use of this filter in the
directory

    Insight/Examples/Registration/
                        DeformableRegistration2.cxx
                        DeformableRegistration3.cxx
                        DeformableRegistration5.cxx
                        LandmarkWarping2.cxx


In order to create the input image with a rectilinear
grid you can use LinearImageIterators. Please read the
chapter on ImageIterators in the ITK SoftwareGuide.
