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.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
