An l0-norm based color image deblurring model under mixed random-valued impulse and Gaussian noise

•A nonconvex nonsmooth model for deblurring color images with mixed randomvalued impulse and Gaussian noise is proposed.•The l0-l2 data-fidelity terms facilitate efficient elimination of blurring and mixed noise.•Total variation enables adequate denoising while preserving edges.•A proximal alternati...
