Dataset A (2D): comparison of denoising algorithms. First, we compare conventional denoisers (left column) to our MH method (right column). Second, we compare the results obtained by applying three different 2D denoising algorithms: BM3D, NL-Bayes, and ROF denoising. On the bottom, we evaluate the performance in terms of PSNR and CCC values. It turns out that our MH method performs better than conventional denoisers in all situations.
