Group sparse representation and saturation-value total variation based color image denoising under multiplicative noise

Group sparse representation and saturation-value total variation based color image denoising under multiplicative noise

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). The data-...
