You should pick an [example](https://itk.org/ITKExamples/src/Registration/index.html) which is closest to your requirements and modify it. Look at the software guide to learn more about how [registration](https://itk.org/ITKSoftwareGuide/html/Book2/ITKSoftwareGuide-Book2ch3.html) is implemented/organized in ITK.
