Table 2 Registration metrics for the evaluation of the used method (affine + variational) by comparison to the free form deformation model with two sets of parameters (FFD₁ and FFD₂): precision p, recall r, F-measure, and mutual information m_i. The variational method offers the best compromise between intensity fidelity and shape similarity
