A new method based on coupling with shock filters and anisotropic diffusion is presented for image enhancement and denoising in this work. A new improved shock filters term and a new fidelity term, which are produced adaptive magnitude from image structural information, are proposed for the image enhancement and denoising. The method can not only well restrain noise but also enhance edge and keep much more structural details of an image, and the computed time of this algorithm is greatly shortened. The form of discretization is directly given in this paper. Experimental results show that the effectiveness for image enhancement and denoising with our method is better.
