MorphGrayGetSize

Computes the size of the gray-kernel morphology state structure.

Syntax

IppStatus ippiMorphGrayGetSize_8u_C1R(IppiSize roiSize, const Ipp32s* pMask, IppiSize maskSize, int* pSize);

IppStatus ippiMorphAdvGetSize_32f_C1R(IppiSize roiSize, const Ipp32f* pMask, IppiSize maskSize, int* pSize);

Parameters

roiSize	Maximal size of the image ROI in pixels, that can be processed using the allocated structure.
pMask	Pointer to the mask.
maskSize	Size of the mask in pixels.
pSize	Pointer to the size of the advanced morphology state structure.

Description

The function ippiMorphGrayGetSize is declared in the ippcv.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function computes the size of the morphology state structure pState for gray-kernel dilation and erosion. This function should be run prior to the function MorphGrayInit.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsSizeErr	Indicates an error condition if maskSize or if roiSize has a field with a zero or negative value.
