Image denoising: learning noise distribution via PDE-constrained optimization
Juan-Carlos De los Reyes, Carola-Bibiane Schönlieb
We propose a PDE-constrained optimization approach for the determination of noise distribution in total variation (TV) image denoising. An optimization problem for the determinatio…

A combined first and second order variational approach for image reconstruction
Konstantinos Papafitsoros, Carola-Bibiane Schönlieb
In this paper we study a variational problem in the space of functions of bounded Hessian. Our model constitutes a straightforward higher-order extension of the well known ROF func…
