On the ROF Model in Rectilinear Anisotropy: Piecewise Constant Approximation and Universal Minimality
Clemens Kirisits, Eric Setterqvist
We prove that the distance between the minimizer of the -anisotropic Rudin-Osher-Fatemi (ROF) functional and its minimizer over the space of piecewise constant functi…
