Artificial heavily noised image. (pic 1) Original noise-free image. (pic 2) Heavily noised image with \(\mathrm{SNR}=1.24\). (pic 3) Image restored using the present model with \(\tau=0.21\), \(\lambda=21\), \(K=7\), \(\sigma= 1.5\), and 662 iterations, \(\mathrm{SNR}=10.40\). (pic 4) Image restored using the (1.1)-(1.2), (1.2) with \(\tau=0.3\), \(\lambda=21\), \(K=7\), and 5,151 iterations, \(\mathrm{SNR}=9.06\).
