Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.
Reimplemented from itk::Object.

Adjust the landmark stiffness matrix based on the change of the number of the landmarks. The argument depend on the number of landmarks and the number of node in the mesh. This method update the value of the ponderation based on a previous ponderation value and the computed Landmark Tensor ponderation returned by the GetLandmarkTensorPonderation() method.
