On the optimality of convergence conditions for multiscale decompositions in imaging and inverse problems
Simone Rebegoldi, Luca Rondi
We consider the multiscale procedure developed by Modin, Nachman and Rondi, Adv. Math. (2019), for inverse problems, which was inspired by the multiscale decomposition of images by…

A counterexample to convergence for multiscale decompositions
Simone Rebegoldi, Luca Rondi
We discuss the convergence of the multiscale procedure by Modin, Nachman and Rondi, Adv. Math. (2019), which extended to inverse problems the multiscale decomposition of images by…
