    We show how, using optimal transport, one can recast many different inverse problems arising in optics into solving a non-linear system of equations namely a discrete version of the so-called Monge-Ampère equation. Many simulated and fabricated results are presented.

  2. An algorithm for optimal transport between a simplex soup and a point cloud
    Quentin Mérigot, Jocelyn Meyron, Boris Thibert,
    SIAM Journal on Imaging Sciences (SIIMS), doi
    arXiv preprint.
    We prove the convergence of a damped Newton's method to solve the optimal transport problem between a source probability measure supported on a finite union of simplices and a finitely supported target probability measure. Applications include optimal quantization of triangulated surfaces, point set registration on a mesh or remeshing.
