Iterative TV minimization on the graph
Japhet Niyobuhungiro, Eric Setterqvist, Freddie Åström +1
We define the space of functions of bounded variation () on the graph. Using the notion of divergence of flows on graphs, we show that the unit ball of the dual space to i…
Preservation of Piecewise Constancy under TV Regularization with Rectilinear Anisotropy
Clemens Kirisits, Eric Setterqvist, Otmar Scherzer
A recent result by Lasica, Moll and Mucha about the -anisotropic Rudin-Osher-Fatemi model in asserts that the solution is piecewise constant on a rectilinear…
Invariant -minimal sets and total variation denoising on graphs
Clemens Kirisits, Otmar Scherzer, Eric Setterqvist
Total variation flow, total variation regularization and the taut string algorithm are known to be equivalent filters for one-dimensional discrete signals. In addition, the filtere…
