Parameters
pSrc
Pointer to the source image ROI.
srcStep
Distance in bytes between starts of consecutive lines in the source image.
pDst
Pointer to the destination image ROI.
dstStep
Distance in bytes between starts of consecutive lines in the destination image.
roiSize
Size of the source and destination image ROI.
borderType
Type of border; the possible value is
ippBorderRepl
, which means that a replicated border is used.
srcBitOffset
Offset, in bits, from the first byte of the source image.
dstBitOffset
Offset, in bits, from the first byte of the destination image.
pSpec
Pointer to the specification structure.
pBuffer
Pointer to the external work buffer.
borderValue
,
borderValue[3]
,
borderValue[4]
Constant value to assign to pixels of the constant border. This parameter is applicable only to the
ippBorderConst
border type.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function calculates a morphological gradient of a rectangular ROI area inside a one-, three-, or four-channel 2D image using a specified in the advanced morphology specification structure mask and anchor cell. The structure must be initialized by
MorphAdvInit
beforehand.
The result is equivalent to the subtraction of an opened source image from a closed source image.
The function can process only images with ROI that does not exceed the maximum width and height
roiSize
specified by the initialization functions.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr
Indicates an error condition if one of the specified pointers is
NULL
.
ippStsSizeErr
Indicates an error condition if
roiSize
has a field with a zero or negative value, or if one of ROI width or height is greater than corresponding size of ROI passed to the initialization functions.
ippStsStepErr
Indicates an error condition if
srcStep
or
dstStep
is less than
roiSize.width
*
<pixelSize>
.
ippStsNotEvenStepErr
Indicates an error condition if one of the step values is not divisible by 4 for floating-point images.
ippStsBorderErr
Indicates an error condition if
borderType
has an illegal value.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
