Image Processing for Low-Dose CT via Novel Anisotropic Fourth-Order Diffusion Model

Image Processing for Low-Dose CT via Novel Anisotropic Fourth-Order Diffusion Model

Low-dose CT images contain severe mottle noise and streak artifacts, which seriously affect the physician’s diagnosis of the disease. Hence, in this paper, we propose a novel anisotropic fourth-order diffusion model for low-dose CT image processing. The proposed diffusion model uses both...
