An Adaptive Total Generalized Variation Model with Augmented Lagrangian Method for Image Denoising

Figure 6

PSNR versus 𝛽 for (a) Lena image under Gaussian noise of 𝜎=30 and (b) Peppers image under Gaussian noise of 𝜎=40, respectively. The absolute error between the maximum and the minimum of PSNR for each image is less than 0.18 dB.
