Preconditioning Technique for an Image Deblurring Problem with the Total Fractional-Order Variation Model

Total fractional-order variation (TFOV) in image deblurring problems can reduce/remove the staircase problems observed with the image deblurring technique by using the standard total variation (TV) model. However, the discretization of the Euler–Lagrange equations associated with the TFOV model gene...
