Deformable registration

Development
1

Hi,

I am trying to do a deformable registration after doing a landmark-based registration between a triangular simplex mesh and CT image.

In the snapshot, after using a landmark-based registration I got the registered bone mesh(The colored outline) and volume. To do a perfectly aligned registration, I want to do a deformation.
Is it possible to do a deformable bone mesh registration using VTK?
I have attached the files in the link.

Yes, VTK can very nicely transform meshes and images using the same transform. Reslice image takes care of images, while transform polydata filter handles meshes.

Could you please suggest few examples and or methods.

You can google for the words that I wrote above to find the exact class names and examples. If you want to give it a try before starting programming then there is a nice GUI for all these in 3D Slicer (just drag-and-drop the transform and images to the application window then go to Transforms module to choose what transform to apply to what).
