CrossCorrNormGetBufferSize

Computes the size of the work buffer for the ippiCrossCorrNorm function.

Syntax

IppStatus ippiCrossCorrNormGetBufferSize (IppiSize srcRoiSize, IppiSize tplRoiSize, IppEnum algType, int* pBufferSize);

Domain Dependencies

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

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

Parameters

srcRoiSize, tplRoiSize	Size of the source/template ROI in pixels.
algType	Bit-field mask for the algorithm type definition. Possible values are the results of composition of the IppAlgType, IppiROIShape, and IppiNormOp values.
pBufferSize	Pointer to the size of the work buffer.

Description

The ippiCrossCorrNormGetBufferSize function computes the size, in bytes, of the external work buffer needed for the function that performs two-dimensional cross-correlation. The result is stored in the pBufferSize parameter.

Return Values

ippStsNoErr	Indicates no error.
ippStsSizeErr	Indicates an error when: srcRoiSize or tplRoiSize is negative, or equal to zero the value of srcRoiSize is less than the corresponding value of tplRoiSize.
ippStsAlgTypeErr	Indicates an error when: the result of the bitwise AND operation between the algType and ippAlgMask differs from the ippAlgAuto, ippAlgDirect, or ippAlgFFT values. the result of the bitwise AND operation between the algType and ippiROIMask differs from the ippiROIFull, ippiROISame, or ippiROIValid values. the result of the bitwise AND operation between the algType and ippiNormMask differs from the ippiNormNone, ippiNorm, or ippiNormCoefficient values.
ippStsNullPtrErr	Indicates an error when pBufferSize is NULL.
