An Edge-Preserved Image Denoising Algorithm Based on Local Adaptive Regularization
Figure 2
Comparison of Gaussian noisy image and denoising results by different methods. (The SNR value of this comparison is as follows: noisy image SNR = 7.5325, classical TV denoising SNR = 13.5687, bilateral filter denoising SNR = 13.3146, the proposed method in [4] SNR = 14.1413, and the proposed method in this paper SNR = 14.2835.)
