A Weberized Total Variation Regularization-Based Image Multiplicative Noise Removal Algorithm

Multiplicative noise removal is of momentous significance in coherent imaging systems and various image processing applications. This paper proposes a new nonconvex variational model for multiplicative noise removal under the Weberized total variation (TV) regularization framework. Then, we propose...
