From: Image Variational Denoising Using Gradient Fidelity on Curvelet Shrinkage
The subimages of the original, noisy, and restored "Lena": (a) the original image; (b) the noisy image (SNR = 1. 54, MSSIM = 0.15); (c) the restored image by the curvelet shrinkage method (SNR = 13.72, MSSIM = 0.79); (d) the restored image by using the "TV" model (SNR = 12.94, MSSIM = 0.71); (e) the restored image by using the "TVGF" model (SNR = 12.01, MSSIM = 0.61); (f) the restored image by using the proposed model (SNR = 14.36, MSSIM = 0.82).
