This metric is a non-commutative analog of the 2-Wasserstein metric, and in several interesting cases we are able to show, in analogy with work of Otto on gradient flows with respect to the classical 2-Wasserstein metric, that the relative entropy is strictly and uniformly convex with respect to the Riemannian metric introduced here.

The source term is also incorporated in the path energy by means of its squared L2-norm in time of a functional with linear growth in space. This extension of the original transport model enables local density modulations, which is a desirable feature in applications such as image warping and blending. A key advantage of the use of a functional with linear growth in space is that it allows for singular sources and sinks, which can be supported on points or lines. On a technical level, the L2-norm in time ensures a disintegration of the source in time, which we use to obtain the well-posedness of the model and the existence of geodesic paths. The numerical discretization is based on the proximal splitting approach [18] and selected numerical test cases show the potential of the proposed approach. Furthermore, the approach is applied to the warping and blending of textures."}],"year":"2017","citation":{"short":"J. Maas, M. Rumpf, S. Simon, in:, F. Lauze, Y. Dong, A.

Using different methods, such bounds have recently been obtained in several examples (e.g., 1-dimensional birth and death chains, product chains, Bernoulli–Laplace models, and random transposition models). However, a general method to obtain discrete Ricci bounds had been lacking. Our method covers all of the examples above. In addition we obtain new Ricci curvature bounds for zero-range processes on the complete graph. The method is inspired by recent work of Caputo, Dai Pra and Posta on discrete functional inequalities."}],"doi":"10.1214/15-AAP1133","day":"01","language":[{"iso":"eng"}],"publication":"The Annals of Applied Probability","month":"06","oa_version":"Preprint","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","status":"public","main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/1501.00562"}],"date_published":"2016-06-01T00:00:00Z","type":"journal_article","oa":1,"publist_id":"5748"},{"issue":"7","author":[{"id":"4C5696CE-F248-11E8-B48F-1D18A9856A87","last_name":"Maas","first_name":"Jan","full_name":"Maas, Jan","orcid":"0000-0002-0845-1338"},{"last_name":"Matthes","first_name":"Daniel","full_name":"Matthes, Daniel"}],"scopus_import":1,"_id":"1261","intvolume":"        29","title":"Long-time behavior of a finite volume discretization for a fourth order diffusion equation","date_created":"2018-12-11T11:51:00Z","department":[{"_id":"JaMa"}],"publication_status":"published","quality_controlled":"1","page":"1992 - 2023","publisher":"IOP Publishing Ltd.","year":"2016","citation":{"ista":"Maas J, Matthes D. 2016.

For a pair of given input images geodesic paths in the space of images are defined as minimizers of a resulting path energy. To this end, the underlying Riemannian metric measures the rate of transport cost and the rate of viscous dissipation. Furthermore, the model is capable to deal with strongly varying image contrast and explicitly allows for sources and sinks in the transport equations which are incorporated in the metric related to the metamorphosis approach by Trouvé and Younes. In the non-viscous case with source term existence of geodesic paths is proven in the space of measures. The proposed model is explored on the range from merely optimal transport to strongly dissipative dynamics. For this model a robust and effective variational time discretization of geodesic paths is proposed. This requires to minimize a discrete path energy consisting of a sum of consecutive image matching functionals. These functionals are defined on corresponding pairs of intensity functions and on associated pairwise matching deformations. Existence of time discrete geodesics is demonstrated. Furthermore, a finite element implementation is proposed and applied to instructive test cases and to real images. In the non-viscous case this is compared to the algorithm proposed by Benamou and Brenier including a discretization of the source term. Finally, the model is generalized to define discrete weighted barycentres with applications to textures and objects.","lang":"eng"}],"arxiv":1,"doi":"10.1051/m2an/2015043","day":"01","volume":49,"acknowledgement":"The authors acknowledge support of the Collaborative Research Centre 1060 funded by the German Science foundation.
