Figure 5: PSNR plot of denoised images for various η values. 5(a) is results from images with noise of standard deviation of
10 from the original images. 5(b) is results from images with noise of standard deivation of 20 from the original images.
local intensity differences based on a boundary value.
To properly apply this method, selection of the bound-
ary value was also suggested. Using the proposed
method, higher PSNR results and clearer denoised
images were obtained compared to the results from
the non-local total variation regularization and to the
results from the non-local H
1
regularization.
