A New Study of Blind Deconvolution with Implicit Incorporation of Nonnegativity Constraints
Figure 6
Experimental results on Images 3-4 with Blur 2, restored using Algorithm 2. Row 1, l-r for Image 3: the PSNR/SNR is increased by 16.77/5.71 from 10.07/15.5 to 26.84/21.21. Row 2, l-r for Image 4: the PSNR/SNR is increased by 4.36/4.67 from 17.79/13.5 to 22.15/18.17. In this more challenging case of Gaussian blur, our model is capable of restoring some detailed features, including the books in the background of (c) and the buildings in (f).
