% K-SVD 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 K-SVD 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. - 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 K-SVD image denoising. ./ksvd (1) you can moreover want to compute the bias (algorithm applied to the original image). To do this, use doBias = true. There are multiple ways to run the code: (2) if you want to use the speed-up trick, use doSpeedUp = true (recommanded) (3) if you want to obtain the best PSNR result, use doBestPSNR = true Example, run ./ksvd cinput.png 10 ImNoisy.png ImDenoised.png ImDiff.png ImBias.png ImDiffBias.png 0 1 0 # 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.
