An Inverse Problem: Recovery of a Distribution Using Wasserstein Barycenter


  • Eustasio DEL BARRIO
  • Jean-Michel LOUBES


We propose to study the inverse problem of estimating a distribution observed through an image by a parametric operator. We construct first estimators for the individual parameters of the operators and study their behaviour, then we invert the approximated operator to obtain and estimator of the distribution. The estimation procedure is given by the minimization of a criterion that compares the alignment of the operator to the Wasserstein barycenter of these warped distributions.
