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-fidelity term is suitable for handling heavy multipl

Soil microbial community structure and diversity are largely influenced by soil pH and nutrient quality in 78-year-old tree plantations

Forest plantations have been recognised as a key strategy management tool for stocking carbon (C) in soils, thereby contributing to climate warming mitigation.However, long-term ecological consequences of anthropogenic forest plantations on the community structure and diversity of soil microorganisms and the underlying mechanisms in determining the
