Abstract : Benamou and Brenier formulation of Monge transportation problem has proven to be of great interest in image processing to compute warpings and distances between pair of images. In some applications, however, the built-in minimization of kinetic energy does not give satisfactory results. In particular cases where some specific regions represent physical objects, it does not make sense, as produces genuine optimal transport, to split, merge or arbitrarily deform these regions along the optimal path. The aim of this work is to introduce several extended energies to take care of physical properties of the image in the interpolation process. We present algorithms to compute approximations of the corresponding generalized optimal transportation plans.
