% BM3D image denoising. # ABOUT * Author : Marc Lebrun * Copyright : (C) 2011 IPOL Image Processing On Line http://www.ipol.im/ * Licence : GPL v3+, see GPLv3.txt # OVERVIEW This source code provides an implementation of the BM3D image denoising. # UNIX/LINUX/MAC USER GUIDE The code is compilable on Unix/Linux and Mac OS. - Compilation. Automated compilation requires the make program. - Library. This code requires the libpng library and the fftw library. - Image format. Only the PNG format is supported. ------------------------------------------------------------------------- Usage: 1. Download the code package and extract it. Go to that directory. 2. Compile the source code (on Unix/Linux/Mac OS). There are two ways to compile the code. (1) RECOMMENDED, with Open Multi-Processing multithread parallelization (http://openmp.org/). Roughly speaking, it accelerates the program using the multiple processors in the computer. Run make OMP=1 OR (2) If the complier does not support OpenMp, run make 3. Run BM3D image denoising. ./BM3Ddenoising The generic way to run the code is: ./BM3Ddenoising cinput.png sigma ImNoisy.png ImBasic.png ImDenoised.png ImDiff.png ImBias.png ImDiffBias.png computeBias 2DtransformStep1 useSD1 2DtransformStep2 useSD2 ColorSpace with : - cinput.png is a noise-free image; - sigma is the value of the noise which will be added to cinput.png; - ImNoisy.png will contain the noisy image; - ImBasic.png will contain the result of the first step of the algorithm; - ImDenoised.png will contain the final result of the algorithm; - ImDiff.png will contain the difference between cinput.png and ImDenoised.png; - ImBias.png will contain the result of the algorithm applied on cinput.png; - ImDiffBias.png will contain the difference between cinput.png and ImBias.png; - computeBias : see (3); - 2DtransformStep1: choice of the 2D transform which will be applied in the first step of the algorithm. See (4); - useSD1 : see (1) below; - 2DtransformStep2: choice of the 2D transform which will be applied in the second step of the algorithm. See (4); - useSD2 : see (2); - ColorSpace : choice of the color space on which the image will be applied. See (5). There are multiple ways to run the code: (1) for the first step, users can choose if they prefer to use standard variation for the weighted aggregation (useSD1 = 1) (2) for the second step, users can choose if they prefer to use standard variation for the weighted aggregation (useSD2 = 1) (3) you can moreover want to compute the bias (algorithm applied to the original image). To do this, use computeBias = 1. (4) you can choose the DCT transform or the Bior1.5 transform for the 2D transform in the step 1 (tau_2D_hard = dct or bior) and/or the step 2. (tau_2d_wien = dct or bior). (5) you can choose the colorspace for both steps between : rgb, yuv, ycbcr and opp. Example, run ./BM3Ddenoising cinput.png 10 ImNoisy.png ImBasic.png ImDenoised.png ImDiff.png ImBias.png ImDiffBias.png 1 bior 0 dct 1 opp # ABOUT THIS FILE Copyright 2011 IPOL Image Processing On Line http://www.ipol.im/ 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.
