Denoising of the Lena image using different methods. Top left: the original image. Top right: a noisy image with Gaussian noise (σ=10). Middle left: the denoised image by CEP- L 2 with PSNR =32.3446. Middle right: by NLCEP- L 2 with PSNR =33.0145. Bottom left: the detail of Lena image denoised by CEP- L 2 (magnified by 1.5 times).
