SegmentGradientGetBufferSize

Computes the size of the working buffer for the gradient segmentation.

Syntax

IppStatus ippiSegmentGradientGetBufferSize_8u_C1R(IppiSize roiSize, int* pBufferSize);

IppStatus ippiSegmentGradientGetBufferSize_8u_C3R(IppiSize roiSize, int* pBufSize);

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h, ippi.h

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

Parameters

roiSize
Size of the source image ROI in pixels.
pBufSize, pBufferSize
Pointer to the computed size of the working buffer.

Description

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

This function computes the size of the working buffer required for the ippiSegmentGradient function. The buffer with the length pBufSize[0] can be used to segment images with width and/or height that is equal to or less than the corresponding field of the parameter roiSize.

Return Values

ippStsNoErr

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

ippStsNullPtrErr

Indicates an error condition if the pointer pBufSize is NULL.

ippStsSizeErr

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