Developer Reference for Intel® Integrated Performance Primitives 2018

LBPImageMode

Calculates LBP of the image according to the specified mode.

Syntax

IppStatus ippiLBPImageMode3x3_<mod>(const Ipp<srcDatatype>* pSrc, int srcStep, Ipp<dstDatatype>* pDst, int dstStep, IppiSize dstRoiSize, int mode, IppiBorderType borderType, const Ipp<srcDatatype>* borderValue);

Supported values for mod:

8u_C1R 32f8u_C1R

IppStatus ippiLBPImageMode5x5_<mod>(const Ipp<srcDatatype>* pSrc, int srcStep, Ipp<dstDatatype>* pDst, int dstStep, IppiSize dstRoiSize, int mode, IppiBorderType borderType, const Ipp<srcDatatype>* borderValue);

8u_C1R 8u16u_C1R 32f8u_C1R 32f16u_C1R

Libraries: ippcore.lib, ippvm.lib, ipps.lib

Parameters

pSrc

Pointer to the source image ROI.

srcStep

Distance, in bytes, between the starting points of consecutive lines in the source image.

pDst

Pointer to the destination image ROI.

dstStep

Distance, in bytes, between the starting points of consecutive lines in the destination image.

dstRoiSize

Size of the destination ROI, in pixels.

mode

Mode for LBP calculation. Supported values are 0, 1, 2, 3.

borderType

Type of border. Possible values are:

ippBorderRepl

Border is replicated from the edge pixels.

ippBorderInMem

Border is obtained from the source image pixels in memory.

Mixed borders are also supported. They can be obtained by the bitwise operation OR between ippBorderRepl and ippBorderInMemTop, ippBorderInMemBottom, ippBorderInMemLeft, ippBorderInMemRight.

borderValue

Constant value to assign to pixels of the constant border. This parameter is applicable only to the ippBorderConst border type.

Description

These functions operate with ROI (see Regions of Interest in Intel IPP).

The ippiLBPImageMode3x3 and ippiLBPImageMode5x5 functions calculate LBP of the pSrc image ROI according to the mode value. The result is stored in the pDst destination image.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error when one of the specified pointers is NULL.

ippStsSizeErr

Indicates an error if dstRoiSize has a field with a zero or negative value.

ippStsBadArgErr

Indicates an error when border has an illegal value.
