\brief a class for the evaluation of a pseudo ground truth of a perfusion series
This class implements the optimization problem required for Ground Thruth Estimation
as described in
Chao Li and Ying Sun, Nonrigid Registration of Myocardial Perfusion MRI Using Pseudo Ground Truth,
In Proc. Medical Image Computing and Computer-Assisted Intervention – MICCAI 2009,
165-172, 2009
For its use see the class C2DGroundTruthEvaluator.
