% Non local means denoising # ABOUT * Author : Antoni Buades * Copyright : (C) 2009, 2010 IPOL Image Processing On Line http://www.ipol.im/ * Licence - nlmeans_ipol.cpp, libdenoising.cpp and libdenoising.h may be linked to the EP patent 1,749,278 by A.

Only 8bit RGB PNG images are handled. # REQUIREMENTS The code is written in ANSI C and C++, and should compile on any system with an ANSI C/C++ compiler. The libpng header and libraries are required on the system for compilation and execution. The implementation uses OPENMP which not supported by old versions of gcc (older than the 4.2). # COMPILATION Simply use the provided makefile, with the command `make`. # USAGE usage: nlmeans_ipol image sigma noisy denoised `nlmeans_ipol ` takes 4 parameter: `nlmeans_ipol in.png sigma noisy.png denoised.png` * `sigma` : the noise standard deviation * `in.png` : initial noise free image * `noisy.png` : noisy image used by the denoising algorithm * `denoised.png` : denoised image # ABOUT THIS FILE Copyright 2009, 2010 IPOL Image Processing On Line http://www.ipol.im/ Author: Antoni Buades Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved.
