This project uses OpenCV (C++) to implement Weiner Filtering simulation It uses the Gaussian function or more specifically its Fourier Transforms (FT) as described in:

Weisstein, Eric W. "Fourier Transform--Gaussian." From MathWorld--A Wolfram Web Resource. http://mathworld.wolfram.com/FourierTransformGaussian.html

The image is first translated where the first and third quadrants are swapped. The second and fourth quadrants are swapped likewise. The FT of the image is compute. It is then multiplied with the FT of the Gaussian. The inverse transform is then translated once again and polluted with noise. Weiner filtering is used to deconvolve the image. The procedure is the same translate, FT the image, multiply by FT of Weiner filter, and translate again.

It was developed on Windows but it uses just OpenCV GUI and hence should work with any OS with OpenCV.
