Note1: For a fast execution, please enable “parfor” using Matlab command “matlabpool”.
Note2: The TNRD software contains mex files. If you encounter problems when running the
denoiser, try to download the TNRD code from the above dropbox link.
Then, copy the files from the directory
YOUR_LOCAL_PATH/TNRD-Codes/TestCodes(denoising-deblocking-SR)/GaussianDenoising
to YOUR_LOCAL_PATH/RED/tnrd_denoising directory.
If you are using mex files for the first time, please run the following in Matlab’s
command window:
>> mex -setup
You will see the following question:
"Would you like mex to locate installed compilers [y]/n?"
>> y
Now you should choose a compiler. Simply choose the first one by clicking
>> 1
Then verify by
>> y
The test images, used to degrade the image, are taken from on the NCSR software.

“Nonlocally Centralized Sparse Representation for Image Restoration”, IEEE-TIP, 2013.
The NCSR code is available in http://www4.comp.polyu.edu.hk/~cslzhang/NCSR.htm.
Also, to have a fair comparison, we use a similar degradation process as done in NCSR.

Demonstration of the image restoration experiments conducted in Y. Romano, M. Elad, and P. Milanfar, “The Little Engine that Could: Regularization by Denoising (RED)“, SIAM Journal on Imaging Sciences, 10(4), 1804–1844, 2017 [arXiv].
The code was tested on Windows 7 and Windows 10, with Matlab R2016a.

The code uses an image denoising algorithm called TNRD, described in Yunjin Chen, and Thomas Pock, “Trainable Nonlinear Reaction Diffusion: A Flexible Framework for Fast and Effective Image Restoration”, IEEE TPAMI 2016. The TNRD code is available in the authors website http://www.escience.cn/people/chenyunjin and downloaded from https://www.dropbox.com/s/8j6b880m6ddxtee/TNRD-Codes.zip?dl=0.
