An Edge-Preserved Image Denoising Algorithm Based on Local Adaptive Regularization
Figure 4
Comparison of different denoising methods of real noisy image. (The SNR value of this comparison is as follows: noisy image SNR = 6.3736, classical TV denoising SNR = 11.4326, bilateral filter denoising SNR = 11.2724, the proposed method in [4] SNR = 11.7538, and the proposed method in this paper SNR = 12.1015.)
