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.","lang":"eng"}],"external_id":{"isi":["000432210900045"]},"author":[{"last_name":"Maas","id":"4C5696CE-F248-11E8-B48F-1D18A9856A87","full_name":"Maas, Jan","orcid":"0000-0002-0845-1338","first_name":"Jan"},{"full_name":"Rumpf, Martin","first_name":"Martin","last_name":"Rumpf"},{"last_name":"Simon","first_name":"Stefan","full_name":"Simon, Stefan"}],"alternative_title":["LNCS"],"publication_identifier":{"issn":["03029743"]},"publisher":"Springer","volume":10302,"publication_status":"published","doi":"10.1007/978-3-319-58771-4_45","citation":{"apa":"Maas, J., Rumpf, M., &#38; Simon, S.
