Let $x_1, ... , x_N$ and $y_1, ... , y_N$ be corresponding template and target landmarks respectively. The program finds an optimal diffeomorphism φ that interpolates the correspondences by minimizing

$y_1, ... , y_N$


where d is a geodesic distance in a group of diffeomorphisms [1]. The algorithm solves the nonlinear Euler equation by a Newton method combined with a shooting procedure [2].
