Class NPPNativeMethods.NPPi.FilterWienerBorder

Noise removal filtering of an image using an adaptive Wiener filter with border control.

Pixels under the source mask are used to generate statistics about the local neighborhood which are then used to control the amount of adaptive noise filtering locally applied.

Currently only the NPP_BORDER_REPLICATE border type operation is supported.
