  • The structure of optimal parameters for image restoration problems 

    de, los Reyes JC; Schönlieb, CB; Valkonen, T (ElsevierJournal of Mathematical Analysis and Applications, 2015-09-16)
    We study the qualitative properties of optimal regularisation parameters in variational models for image restoration. The parameters are solutions of bilevel optimisation problems with the image restoration problem as ...
