Unified Models for Second-Order TV-Type Regularisation in Imaging - A New Perspective Based on Vector Operators

31 Oct 2018 Brinkmann Eva-Maria Burger Martin Grah Joana Sarah

We introduce a novel regulariser based on the natural vector field operations gradient, divergence, curl and shear. For suitable choices of the weighting parameters contained in our model it generalises well-known first- and second-order TV-type regularisation methods including TV, ICTV and TGV$^2$ and enables interpolation between them...
