Adaptive double-phase Rudin--Osher--Fatemi denoising model
Wojciech Górny, MichaÅ Åasica, Alexandros Matsoukas
Even though more than 30 years have passed since the seminal Rudin--Osher--Fatemi (ROF) paper on total variation (TV) denoising, it remains relevant, in particular in scientific ap…

Mosco convergence framework for singular limits of gradient flows on Hilbert spaces with applications
Yoshikazu Giga, MichaÅ Åasica, Piotr Rybka
We consider the question of convergence of a sequence of gradient flows defined on different Hilbert spaces. In order to give meaning to this idea, we introduce a notion of connect…

Euler-Lagrange equations for variable-growth total variation
Wojciech Górny, MichaÅ Åasica, Alexandros Matsoukas
We consider a class of integral functionals with Musielak-Orlicz type variable growth, possibly linear in some regions of the domain. This includes power-type integrands wit…
