Abstract

In this project we were interested in denoising and deconvolution, with an L1 regularization term. A classical method is Total Variation. Based on this method, we change the operator of the regularization. We use Laplacian and compare results of denoising with different kinds of noise. Our method gives better results for some kind of noise and some type of images. Afterwards, we considered using the Hessian in the regularization term.
