Combined higher order non-convex total variation with overlapping group sparsity for impulse noise removal
A typical approach to eliminate impulse noise is to use the l(1)-norm for both the data fidelity term and the regularization terms. However, the l(1)-norm tends to over penalize signal entries which is one of its underpinnings. Hence, we propose a variational model that uses the non-convex l(p)-norm...
