An Improved TV Model for Image Restoration
Yonglin Huang, Yutang Ye, Naosheng Qiao · 2009
A-new total variance of image restoration method is proposed. To overcome blocky effect produced by anisotropic diffusion of TV model, high-order term is added to TV model. The new model has the characteristics of anisotropic diffusion. The experimental results show that the proposed model compare with other models, the PSNR is improved, and the restoration of image look more nature in non-boundary region.
