I am testing ippiFilterWiener_8u_C1R.
It is sure to restore a blurry image.
It returns a more blurry image.
How can I restore a blurry image by using it?

Our FilterWiner is working according to MatLab realization and is useful for removing Gaussian white noise only:

FilterWiner filters an intensity image that has been degraded by constant power additive noise. FilterWiner uses a pixel-wise adaptive Wiener method based on statistics estimated from a local neighborhood of each pixel.

FilterWiner filters an image using pixel-wise adaptive Wiener filtering, using neighborhoods of size m-by-n to estimate the local image mean and standard deviation. The additive noise (Gaussian white noise) power is assumed to be noise.

I understood the function.
Thank you.
