Fast Total-Variation Image Deconvolution with Adaptive Parameter Estimation via Split Bregman Method

Figure 2

ISNR versus runtime for the (left) Abdomen image and (right) Lena image, which are blurred by a 9 × 9 uniform blur with noise variance 0.56² (first row), by a 9 × 9 Gaussian blur with noise variance 2 (second row), and by PSF given by ℎ_𝑖𝑗=1/(1+𝑖²+𝑗²)  (𝑖,𝑗=−7,…,7.) with noise variance 2 (third row).
