The documentation for ippiFilterWiener says the following about the noise parameter:
If this parameter is not defined (noise = 0), then the function estimates the noise level by averaging
through the image of all local variances σi,j, and stores the corresponding values in the noise for further use.
However, when I pass noise=0.0, ippiFilterWiener crashes (with what looks like a corrupted stack). This is with IPP 9.0.2 on Mac OS X and an Intel 2.5 GHz Core 2 Duo MacBook Pro. It happens with all ippiFilterWiener variants I tried. Below, gdb info for ippiFilterWiener_32f_C1R.
