Abstract
According to the principles of image restoration and non-linear constraint optimization, a novel image restoration algorithm based on the anisotropic diffusion model was proposed in this article. Based on the image textures and the gradient characteristics at the image edge, the adaptive anisotropic diffusion model was introduced and the cost function was minimized by the energy minimization scheme. Moreover, the nonlinear equations can be linearized using the fixed-point alternating iterative method. As the experimental results demonstrated, the proposed method can effectively restore the blurred images and enhance the restoration quality.
