A Mathematical Algorithm for Improving the Medical Image
Authors: ,
Abstract: In this paper, we present a hybrid model based on total generalized variation (TGV) and shearlet with
non-quadratic fidelity data terms for blurred images corrupted by impulsive and Poisson noises. Numerical experiments
demonstrate that the proposed can reduce the staircase effect while preserving edges and outperform
classical TV-based models in the peak signal-to-noise ratio (PSNR).
