[ITK] Anchored landmarks with thin plate spline

[Matt McCormick]

Hi Ken,

I talked with Karthik, an author on that paper.  He said that the code
referenced here:

  http://public.kitware.com/pipermail/insight-developers/2005-May/006632.html

is available in this class:

  http://www.itk.org/Doxygen/html/classitk_1_1LandmarkBasedTransformInitializer.html

There are some unit tests that exercise it.


There are also some 3D Slicer modules that use it:

https://www.slicer.org/slicerWiki/index.php/Documentation/4.4/Modules/LandmarkRegistration
Select landmarks and the Rigid option in the module followed by
warping, landmark placement again on rigidly aligned image pairs and
the TPS option in the module, with landmarks placed on the prostate
periphery and several coincident anchors around it.

and

https://www.slicer.org/slicerWiki/index.php/Documentation/4.4/Modules/PlmLANDWARP
Place landmarks on the periphery of the prostate and use the RBF with
locality radius that is half the diameter of the prostate.


HTH,
Matt
