A new development of non-local image denoising using fixed-point iteration for non-convex ℓ(p) sparse optimization
We proposed a new efficient image denoising scheme, which mainly leads to four important contributions whose approaches are different from existing ones. The first is to show the equivalence between the group-based sparse representation and the Schatten-p norm minimization problem, so that the spars...
