CrossCorrNormGetBufferSize

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

Syntax

IppStatus ippiCrossCorrNormGetBufferSize (IppiSize
srcRoiSize
, IppiSize
tplRoiSize
, IppEnum
algType
, int*
pBufferSize
);
Include Files
ippi.h
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.
