An image denoising method based on 4th order PDE and pure anisotropic diffusion
摘要
Abstract
This paper proposes an image denoising method based on 4th order PDE and pure anisotropic diffusion,which pure anisotropic diffusion can remove salt-pepper noises while protecting edges well and 4th order PDE can avoid staircase effects and protect the small veins.Our model solves the excessive diffusion problem at smooth regions in pure anisotropic diffusion model.Meanwhile,our model overcomes the shortage of 4th order PDE model that tends to lose much edge information.Our model solves image denoising,and keeps the edge and the veins detail information of the picture.关键词
