Analysis of a new variational model for multiplicative noise removal

Abstract: In this paper we consider a new variational model for multiplicative noise removal. We prove the existence and uniqueness of the minimizer for the variational problem. Furthermore, we derive the existence and uniqueness of weak solutions for the associated evolution equation. Finally, some numerical experiments are shown to compare the proposed model with the model given by Aubert and Aujol. [Copyright &y& Elsevier]
