[Insight-users] Resampling image using transform parameters from VersorRigid3DTransform

[Luis Ibanez]

Hi Shahab,

You will find many examples on how to use the ResampleImageFilter
in the ITK Software Guide:


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

In particular in section 6.9.4, "Resample Image Filter".
In pdf-page 254-284.

The source code of these examples is available in the directory:

            Insight/Examples/Filtering


You will also find many examples on how to use resampling after
registration in the ITK Software Guide in the chapter:

Chapter 8: "Registration", pdf-page 347-534.

The source code of these examples is available in the directory:


             Insight/Examples/Registration


In particular you should look at
Section: 8.6.4, "Rigid Transform in 3D", in pdf-page 398,
and the associated example:


             Insight/
                Examples/
                     Registration/
                          ImageRegistration8.cxx




Note that, since you are resampling a binary image, you should
use a NearestNeighborInterpolator, in order to ensure that the
resampled image is also binary.


This is a typical task in Atlas-Based segmentation.



    Regards,


       Luis
