Detailed Description

class shapeworks::EigenThinPlateSplineKernelTransform;

Thin plate spline transform whose weights are solved with Eigen.

ITK builds a 3(N+4) square system and solves it with a netlib SVD, which takes about an hour at N=2048. The TPS kernel is |r| times the identity, so that system is three independent (N+4) square systems sharing one matrix. Factoring that matrix once is several thousand times faster and gives the same weights.
