PPB_NAKAGAMI/NLSAR: Probabilistic Patch-Based filter for Nakagami-Rayleigh noise ================================================================================ Revision: 26 May 2012 Author: Charles Deledalle Web page: http://www.ceremade.dauphine.fr/~deledall/ppb.php This MATLAB software implements the denoising algorithm (the Probabilistic Patch-Based filter) for images damaged by multiplicative Nakagami-Rayleigh noise as presented in: "Iterative Weighted Maximum Likelihood Denoising with Probabilistic Patch-Based Weights", C-A. Deledalle, L. Denis and F. Tupin, IEEE Trans. on Image Processing, vol. 18, no. 12, pp. 2661-2672, December 2009. It also corresponds to the NL-SAR filter: "A non-local approach for SAR and interferometric SAR denoising", C-A. Deledalle, Florence Tupin and Loc Denis, in the proceedings of IGARSS, Honolulu, Hawaii, USA, July 2010. This software is free and should be used only for nonprofit purposes. Any unauthorized use of this software for industrial or profit-oriented activities is expressively prohibited. The program has been written for MATLAB with the ImageProcessing Toolbox for Linux 32-bit or ***-bit and Windows 32-bit or ***-bit. The following program files are present: - ppbNakagami.mex*: A Mex function wich performs one iteration of the denoising algorithm. - ppb_nakagami.m: A matlab function wich calls the ppbNakagami.mexglx program to perform the iterative denoising. This function realize also a wrapping of the arguments which can be then given as described in our paper. Please refer to our paper for a more detailed description of the arguments. Note that this function ables to treat large images by preserving memory thanks to a block processing on 1024x1024 subimages. - example_nakagami.m: An example of how to use the PPB filter. It denoises the Lena image (lena.png) corrupted by multiplicative Nakagami-Rayleigh noise with equivalent number of look 3. The PPB filter is used with 2 sets of parameters. One applies the non-iterative PPB filter, the other one performs 4 iteration of the PPB filter with an initial estimate computing also with the PPB filter with a smaller search window size. - psnr.m: Computes the PSNR values. - snr.m: Computes the SNR values. - plotimage.m: Plot a grayscale image with pixel values ranged on [0..255]. - plotimage_sar.m: Plot a SAR amplitude image by rescaling the range of the image on the intervale [0..mean + 3 sigma].
