In this article. we propose a novel group-based sparse representation (GSR) model for restoring color images in the presence of multiplicative noise. This model consists of a convex data-fidelity term. and two regularizations including GSR and saturation-value-based total variation (SVTV). https://www.lightemupsequences.com/deal-find-14K-Gold-plated-Lobster-Closure-Freshwater-Pearl-Bracelet-super-grab/
