MorphologyBorderInit

Initializes the morphology specification structure for erosion or dilation operations.

Syntax

IppStatus ippiMorphologyBorderInit_<mod>(IppiSize roiSize, const Ipp8u* pMask, IppiSize maskSize, IppiMorphState* pSpec, Ipp8u* pBuffer);

Supported values for mod:

1u_C1R	8u_C1R	16u_C1R	16s_C1R	32f_C1R
	8u_C3R			32f_C3R
	8u_C4R			32f_C4R

Parameters

roiSize	Size of the image ROI, in pixels.
pMask	Pointer to the mask.
maskSize	Size of the mask, in pixels.
pSpec	Pointer to the specification structure.
pBuffer	Pointer to the external buffer required for dilation or erosion operations.

Description

This function operates with ROI.

This function initializes the specification structure pSpec in the external buffer. Before using this function, you need to compute the size of the specification structure using the MorphologyBorderGetSize function. This structure is used by the ippiDilateBorder and ippiErodeBorder functions that perform morphological operations on the source image pixels corresponding to non-zero values of the structuring element (mask) pMask.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsSizeErr	Indicates an error when maskSize has a field with a zero or negative value, or if width or height of roiSize is less than 1.
