We introduce a locally adaptive parameter selection method for total variation regularization applied to image denoising. The algorithm iteratively updates the regularization parameter depending on the local smoothness of the outcome of the previous smoothing step. In addition, we propose an anisotropic total variation regularization step for edge enhancement. Test examples demonstrate the capability of our method to deal with varying, unknown noise levels.
