------------------------------------------------------------------ BM3D demo software for image/video restoration and enhancement Public release v1.7.6 (4 February 2011) ------------------------------------------------------------------ Copyright (c) 2006-2011 Tampere University of Technology. All rights reserved. This work should be used for nonprofit purposes only. Authors: Kostadin Dabov Alessandro Foi BM3D web page: http://www.cs.tut.fi/~foi/GCF-BM3D ------------------------------------------------------------------ Contents ------------------------------------------------------------------ The package comprises these functions *) BM3D.m : BM3D grayscale-image denoising [1] *) CBM3D.m : CBM3D RGB-image denoising [2] *) VBM3D.m : VBM3D grayscale-video denoising [3] *) CVBM3D.m : CVBM3D RGB-video denoising *) BM3DSHARP.m : BM3D-SHARP grayscale-image sharepening & denoising [4] *) BM3DDEB.m : BM3D-DEB grayscale-image deblurring [5] For help on how to use these scripts, you can e.g. use "help BM3D" or "help CBM3D". Each demo calls MEX-functions that allow to change all possible parameters used in the algorithm from within the corresponding M-file. ------------------------------------------------------------------ Installation ------------------------------------------------------------------ Unzip both BM3D.zip (contains codes) and BM3D_images.zip (contains test images) in a folder that is in the MATLAB path. ------------------------------------------------------------------ Requirements ------------------------------------------------------------------ *) MS Windows (32 or *** bit), Linux (32 bit or *** bit) or Mac OS X (32 or *** bit) note: CVBM3D supports only 32-bit and ***-bit Windows *) Matlab v.6.5 or later with installed: -- Image Processing Toolbox (for visualization with "imshow"), ------------------------------------------------------------------ What's new in this release ------------------------------------------------------------------ v1.7.6 + Added support for Matlab running on Mac OSX 32-bit + Changed the strong-noise parameters ("vn" profile) in CBM3D.m, as proposed in [6]. v1.7.5 (7 July 2010) + Changed the strong-noise parameters ("vn" profile) in BM3D.m, as proposed in [6]. v1.7.4 (3 May 2010) + Added support for Matlab running on Mac OSX ***-bit v1.7.3 (15 March 2010) + Fixed a problem with writing to AVI files in CVBM3D + Fixed a problem with VBM3D when the input is a 3-D matrix v1.7.2 (8 Dec 2009) + Fixed the output of CVBM3D to be in range [0,255] instead of in range [0,1] v1.7.1 (2 Dec 2009) + Fixed a bug in VBM3D.m introduced in v1.7 that concerns the declipping v1.7 (12 Nov 2009) + Added CVBM3D.m script that performs denoising on RGB-videos with AWGN + Fixed VBM3D.m to use declipping in the case when noisy AVI file is provided v1.6 (17 June 2009) + Made few fixes to the "getTransfMatrix" internal function. If used with default parameters, BM3D no longer requires neither Wavelet, PDE, nor Signal Processing toolbox. + Added support for x86_*** Linux v1.5.1 (20 Nov 2008) + Fixed bugs for older versions of Matlab + Added support for 32-bit Linux + improved the structure of the VBM3D.m script v1.5 (18 Oct 2008) + Added x86_*** version of the MEX-files that run on ***-bit Matlab under Windows + Added a missing function in BM3DDEB.m + Improves some of the comments in the codes + Fixed a bug in VBM3D when only a input noisy video is provided v1.4.1 (26 Feb 2008) + Fixed a bug in the grayscale-image deblurring codes and made these codes compatible with Matlab 7 or newer versions. v1.4 (1 Feb 2008) + Added grayscale-image deblurring v1.3 (12 Oct 2007) + Added grayscale-image joint sharpening and denoising v1.2.1 (4 Sept 2007) + Fixed the output of the VBM3D to be the final Wiener estimate rather than the intermediate basic estimate + Fixed a problem when the original video is provided as a 3D matrix v1.2 (11 June 2007) + Added grayscale-video denoising files v1.1.3 (4 May 2007) + Added support for Linux x86-compatible platforms v1.1.2 + Fixed bugs related with Matlab v.6.1 v1.1.1 (8 March 2007) + Fixed bugs related with Matlab v.6 (e.g., "isfloat" was not available and "imshow" did not work with single precision) + Improved the usage examples shown by executing "help BM3D" or "help CBM3D" MATLAB commands v1.1 (6 March 2007) + Fixed a bug in comparisons of the image sizes, which was causing problems when executing "CBM3D(1,z,sigma);" + Fixed a bug that was causing a crash when the input images are of type "uint8" + Fixed a problem that has caused some versions of imshow to report an error + Fixed few typos in the comments of the functions + Made the parameters of the BM3D and the C-BM3D the same v1.0 (9 December 2006) + Initial version, based on BM3D-DFT [7] package (November 2005) ------------------------------------------------------------------ Publications ------------------------------------------------------------------ [1] K.
