Wiener Filters
Intel IPP functions described in this section perform adaptive noise-removal filtering of an image using Wiener filter [Lim90]. The adaptive filter is more selective than a comparable linear filter in preserving edges and other high frequency parts of an image. Wiener filters are commonly used in image processing applications to remove additive noise from degraded images, to restore a blurry image, and in similar operations.
These functions use a pixel-wise adaptive Wiener method based on statistics estimated from a local neighborhood (mask) of arbitrary size for each pixel.
