Parameters
pSrc
Pointer to the source image ROI.
srcStep
Distance, in bytes, between the starting points of consecutive lines in the source image.
srcBitOffset
Offset, in bits, from the first byte of the source image row.
pDst
Pointer to the destination image ROI.
dstStep
Distance, in bytes, between the starting points of consecutive lines in the destination image.
dstBitOffset
Offset, in bits, from the first byte of the destination image row.
roiSize
Size of the source and destination image ROI.
borderType
Type of border. Possible values are:
ippBorderDefault
The border is set to
ippBorderConst
 with
borderValue
=
MAX_VALUE
, where
MAX_VALUE
=
IPP_MAX_8U/16U/16S/32F/1U
ippBorderRepl
Border is replicated from the edge pixels.
ippBorderMirror
Border pixels are mirrored from the source image boundary pixels.
ippBorderConst
Values of all border pixels are set to a constant.
ippBorderFirstStageInMem
You can use this border type together with the
ippBorderRepl
,
ippBorderMirror
,
ippBorderConst
,
ippBorderDefault
 types using the
|
 operation. For the first stage, border pixels are obtained from the source image pixels in memory. For the second stage, the function uses the border type specified with the
|
 operation.
Mixed borders are also supported. They can be obtained by the bitwise operation
OR
 between any of the
ippBorderRepl
,
ippBorderConst
,
ippBorderDefault
, or
ippBorderMirror
 values and the
ippBorderInMemTop
,
ippBorderInMemBottom
,
ippBorderInMemLeft
,
ippBorderInMemRight
 modifiers.
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.
pMorphSpec
Pointer to the morphology specification structure.
pBuffer
Pointer to the external buffer.
Description
Before using this function, you need to initialize the morphology specification structure using the
ippiMorphInit
 function.
This function performs a black-hat operation on a rectangular ROI area inside a one-, three-, or four-channel 2D image using a specified in the advanced morphology state or specification structure mask and the anchor cell.
The result is equivalent to the subtraction of the initial source image from the closed source image.
The function can only process a ROI that does not exceed the maximum width and height
roiSize
 specified by the initialization functions.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when one of the specified pointers is
NULL
.
ippStsSizeErr
Indicates an error condition when:
  • roiSize
     has a field with a zero or negative value
  • ROI width is more than ROI width passed to the initialization function
ippStsStepErr
Indicates an error condition when
srcStep
 or
dstStep
 is less than
roiSize.width
 * <
pixelSize
>.
ippStsNotEvenStepErr
Indicates an error when one of the step values is not a multiple of an element size.
ippStsBadArgErr
Indicates an error when
borderType
 has an illegal value.
