“…For this purpose, in the case of Gaussian noise we have selected the methods proposed by Cuesta et al [38], fractional-order total variation using proximity algorithm (FTV-PA) [57], R-NL [58], Adaptive Regularization with the Structure Tensor [59]., the full fractional anisotropic diffusion (FFAD) [60] and overlapping group sparsity (OLGS) [40] for comparative analysis. For the case of Poisson noise, comparison is performed with the methods such as fourth-order partial differential equation filter (FOPDEF) [12], TV-Poi [61], OGS-ADM [62], Framelet based (BPID-FR) [63], spatially adaptive (RLSATV) [64] and sparse based (TV-L0) [65]. The work of TV-Poi and OGS-ADM is based on the TV and overlapping group sparsity based prior for Poisson noise image deblurring.…”

“…The mixture model could better suppress the staircase effect and preserve the details in image edges. Recently, overlapping group sparsity has been applied to figure out Cauchy noise [23], Poisson noise [24], and speckle noise [25], demonstrating its effectiveness. The methods mentioned above merely contain gradient information in the vertical and horizontal directions, but ignores gradient in the diagonal and back-diagonal directions.…”

“…First, Rudin et al proposed a nonlinear TV model for denoising of the image as follows 3 : minu:u2+μ2uu022, where μ is the regularization parameter and normalΨfalse(false|normal∇ufalse|false)=false‖normal∇ufalse‖2 is the TV regularizer. Based on this idea, several researchers worked in deblurring process 5‐8 and denoising–deblurring processes 9,10 . The other regularization term that we mentioned here is the Mumford–Shah regularizing functional 2 .…”
