GrayErodeBorder

Performs gray-kernel erosion of an image.

Syntax

IppStatus ippiGrayErodeBorder_8u_C1R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize, IppiBorderType border, IppiMorphGrayState_8u* pState);

IppStatus ippiGrayErodeBorder_32f_C1R(const Ipp32f* pSrc, int srcStep, Ipp32f* pDst, int dstStep, IppiSize roiSize, IppiBorderType border, IppiMorphGrayState_32f* pState);

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

Parameters

pSrc

Pointer to the source image ROI.

srcStep

Distance in bytes between starts of consecutive lines in the source image.

pDst

Pointer to the destination image ROI.

dstStep

Distance in bytes between starts of consecutive lines in the destination image.

roiSize

Size of the source and destination image ROI.

border

Type of border; the possible value is ippBorderRepl, which means that a replicated border is used.

pState

Pointer to the morphology state structure.

Description

This function operates with ROI (see Regions of Interest in Intel IPP).

This function performs gray-kernel erosion of a rectangular ROI area inside a one-channel 2D image using a specified in the gray-kernel morphology state structure pState mask and the anchor cell. This structure must be initialized by MorphGrayInit beforehand.

NOTE:

The structure can be used to process images with ROI that does not exceed the specified maximum width and height roiSize.

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error or a warning.

ippStsNullPtrErr

Indicates an error condition if one of the specified pointers is NULL.

ippStsSizeErr

Indicates an error condition if roiSize has a field with a zero or negative value, or if one of ROI width or height is greater than corresponding size of ROI passed to the initialization functions.

ippStsStepErr

Indicates an error condition if srcStep or dstStep is less than roiSize.width * <pixelSize>.

ippStsNotEvenStepErr

Indicates an error condition if one of the step values is not divisible by 4 for floating-point images.

ippStsBorderErr

Indicates an error condition if border has an illegal value.
