description: Denoise selected images by non-local patch averaging.
This uses the method described in: Non-Local Image Smoothing by Applying Anisotropic Diffusion PDE's in the Space of Patches (D. Tschumperlé, L. Brun), ICIP'09 (https://tschumperle.users.greyc.fr/publications/tschumperle_icip09.pdf).
Uses the 'blur_patch' function from the CImg library.
CImg is a free, open-source library distributed under the CeCILL-C (close to the GNU LGPL) or CeCILL (compatible with the GNU GPL) licenses. It can be used in commercial applications (see http://cimg.eu).
