A novel model of image restoration is proposed. The structure tensor field is calculated after smoothing the noised image by anisotropic diffusion. Then the image is reconstructed by fitting the structure tensor field and the noise image. The proposed method overcomes shortcomings of the classical anisotropic diffusion method. Numerical experiments verify that the proposed method remove noise effectively while preserving structures well.

Key words: image denoising, anisotropic diffusion, structure tensor, additional operator splitting
