Computes the size of the external buffer for ippiFilterMedian function.

Syntax

IppStatus ippiFilterMedianGetBufferSize_32f(IppiSize dstRoiSize, IppiSize maskSize, Ipp32u nChannels, Ipp32u* pBufferSize);

IppStatus ippiFilterMedianGetBufferSize_64f(IppiSize dstRoiSize, IppiSize maskSize, Ipp32u nChannels, Ipp32u* pBufferSize);

Parameters

dstRoiSize	Size of the destination ROI in pixels.
maskSize	Size of the mask in pixels.
nChannels	Number of channels in the image.
pBufferSize	Pointer to the computed value of the external buffer size.

Description

The function ippiFilterMedianGetBufferSize is declared in the ippi.h file. This function computes the size in bytes of an external memory buffer that is required for the function ippiFilterMedian, and stores the result in the pBufferSize.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error.
ippStsNullPtrErr	Indicates an error condition if the pBufferSize pointer is NULL.
ippStsSizeErr	Indicates an error condition if one of the fields of dstRoiSize has a zero or negative value.
ippStsMaskSizeErr	Indicates an error condition if one of the fields of maskSize has a value less than or equal to 1.
ippStsNumChannelsErr	Indicates an error condition if nChannels is not 1, 3 or 4.
