iwiFilterBilateral

Syntax
class IwiFilterBilateralParams: public ::IwiFilterBilateralParams { public: IW_BASE_PARAMS_CONSTRUCTORS(IwiFilterBilateralParams, iwiFilterBilateral_SetDefaultParams) IwiFilterBilateralParams(IppiFilterBilateralType filter = ippiFilterBilateralGauss, IppiDistanceMethodType distMethod = ippDistNormL1) };
IW_DECL_CPP(IppStatus) iwiFilterBilateral( const IwiImage &srcImage, IwiImage &dstImage, int radius, Ipp32f valSquareSigma, Ipp32f posSquareSigma, const IwiFilterBilateralParams &auxParams = IwiFilterBilateralParams(), const IwiBorderType &border = ippBorderRepl, const IwiTile &tile = IwiTile() );
Parameters
srcImage
Reference to the source image.
dstImage
Reference to the destination image.
radius
Radius of the circular neighborhood that contains pixels for calculation.
valSquareSigma
Square of the Sigma value for the factor function for pixel intensity.
posSquareSigma
Square of the Sigma value for the factor function for pixel position.
auxParams
Reference to the auxiliary parameters structure.
border
Extrapolation algorithm for out of image pixels processing. Supported values:
ippBorderConst
Values of all border pixels are set to a constant.
ippBorderRepl
Border is replicated from the edge pixels.
ippBorderMirror
Border pixels are mirrored from the source image boundary pixels.
ippBorderInMem
Border is obtained from the source image pixels in memory.
tile
Reference to the
IwiTile
object for tiling. By default no tiling is used.
Auxiliary Arguments
Argument
Default Value
Description
filter
ippiFilterBilateralGauss
Type of the bilateral filter. The only supported value is
ippiFilterBilateralGauss
.
distMethod
ippDistNormL1
Method for definition of distance between pixel intensities. The only supported value is
ippDistNormL1
.
Description
This function performs bilateral filtering of an image. For more information, refer to the
iwiFilterBilateral
function description in
C Reference
.
Return Values
ippStsNoErr
No errors.
Exception Values
ippStsSizeErr
Values of the
size
fields are illegal.
ippStsBadArgErr
valSquareSigma
or
posSquareSigma
is less than or equal to 0.
ippStsMaskSizeErr
The
radius
value is less than or equal to 0.
ippStsBorderErr
The
border
value is illegal.
ippStsDataTypeErr
The
dataType
value is illegal.
ippStsNumChannelsErr
The
channels
value is illegal.
ippStsNotEvenStepErr
The
srcStep
and/or
dstStep
value is not divisible by size of elements.
ippStsNotSupportedModeErr
The
filter
and/or
distMethod
value is not supported.
ippStsNoMemErr
Failed to allocate memory.
ippStsInplaceModeNotSupportedErr
In-place operation is not supported:
pSrcImage
is equal to
pDstImage
.
ippStsNullPtrErr
At least one of the pointers (except
tile
) is
NULL
.

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.
