Fig. 4From: A new nonlocal variational bi-regularized image restoration model via split Bregman methodDenoising of the Woman image using different methods. Top left: the original image. Top right: a noisy image with Gaussian noise (σ=10). Bottom left: the denoised image by CEP- L 2 with PSNR =29.0179. Bottom right: by NLCEP- L 2 with PSNR =29.2275Back to article page
