Diffusion methods in image processing
It will be explained how diffusion equations enter the field of image denoising and enhancing and discuss, in particular, the famous Perona - Malik problem. Then we motivate and propose time-regularized well-posed versions of the Perona-Malik equations and give numerical evidence for their superiority to the widely used space regularizations.
