Instead of using an Ambrosio-Tortorelli type energy functional, we reformulate the optical flow problem as a multidimensional control problem. The optimal control problem is solved by discretization methods and large-scale optimization techniques. The edge detector can be immediately built from the control variables. We provide three series of numerical examples. The first shows that the mere presence of a gradient restriction has a regularizing effect, while the second demonstrates how to balance the regularizing effects of a term within the objective and the control restriction. The third series of numerical results is concerned with the direct evaluation of a TV-regularization term by introduction of control variables with sign restrictions.}, language = {en} } @techreport{FeindtWoltersBackesetal., author = {Feindt, Peter H. and Wolters, Volkmar and Backes, Gunter and Bahrs, Enno and Brandt, Horst and Dempfle, Leo and Engels, Eve-Marie and Engels, Johannes and Graner, Andreas and Hamm, Ulrich and Herdegen, Matthias and Isselstein, Johannes and Konnert, Monika and Schr{\"o}der, Stefan and Wagner, Sven and W{\"a}tzold, Frank and Wedekind, Helmut}, title = {Verbraucher f{\"u}r die Erhaltung der biologischen Vielfalt in der Landwirtschaft aktivieren!}, publisher = {Bundesanstalt f{\"u}r Landwirtschaft und Ern{\"a}hrung (BLE) Informations- und Koordinationszentrum f{\"u}r Biologische Vielfalt (IBV)}, address = {Bonn}, pages = {12}, language = {de} } @techreport{FeindtWoltersBackesetal., author = {Feindt, Peter H. and Wolters, Volkmar and Backes, Gunter and Bahrs, Enno and Brandt, Horst and Engels, Eve-Marie and Engels, Johannes and Graner, Andreas and Hamm, Ulrich and Herdegen, Matthias and Isselstein, Johannes and Schr{\"o}der, Stefan and Tholen, Ernst and Wagner, Sven and W{\"a}tzold, Frank and Wedekind, Helmut and Wolf, Heino}, title = {Wege zu einem effizienten Waldnaturschutz in Deutschland: Stellungnahme Januar 2020}, address = {Berlin}, pages = {69}, language = {de} } @misc{WaetzoldFeindtBahrsetal., author = {W{\"a}tzold, Frank and Feindt, Peter H. and Bahrs, Enno and Hamm, Ulrich and Isselstein, Johannes and Schr{\"o}der, Stefan and Wagner, Sven and Wedekind, Helmut and Wolters, Volkmar}, title = {Wie die Politik auf die Bedrohung der Biodiversit{\"a}t in Agrarlandschaften durch den Klimawandel reagieren kann.
