Mixed overlapping group sparse and nonconvex fractional-order image restoration algorithm

A nonconvex total variation image denoising model with a double regularization penalty term is proposed in this paper, which effectively overcomes the shortcomings of a single regularization penalty term. The Chambolle-Pock primal-dual algorithm framework is used to solve the model, and the optimal...
