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 (for
1u_C1R
flavor).
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 (for
1u_C1R
flavor).
roiSize
Size of the source and destination image ROI.
borderType
Type of border. Possible values are:
ippBorderRepl
Border is replicated from the edge pixels.
ippBorderInMem
Border is obtained from the source image pixels in memory.
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.
pSpec
Pointer to the specification structure.
pBuffer
Pointer to the external buffer required for dilation operations.
Description
Before using this function, you need to initialize the morphology specification structure using the
MorphAdvInit
function.
This function operates with ROI.
This function performs closing of a rectangular ROI area inside a one-, three-, or four-channel 2D image using the mask specified in the
pSpec
structure.
The result is equivalent to successive dilation of the source image by the structured element (mask) and erosion by the reverted structured element.
This function requires that the image ROI does not exceed the maximum width and height
roiSize
specified by the initialization functions.
Usage example of this function is similar to the example provided with the MorphOpenBorder function description.
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
  • one of the ROI width or height is more than the corresponding size of ROI passed to the initialization functions
  • srcBitOffset
    or
    dstBitOffset
    is less than zero
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 for 16-bit integer images is not divisible by 2.
ippStsBorderErr
Indicates an error condition if
borderType
has an illegal value.

Example

The code example below demonstrates how to use the
ippiMorphAdvGetSize_16u_C1R
,
ippiMorphAdvInit_16u_C1R
, and
ippiMorphCloseBorder_16u_C1R
functions.
IppStatus func_MorfCloseBorder() { IppiMorphAdvState* pSpec = NULL; Ipp8u* pBuffer = NULL; IppiSize roiSize = {5, 5}; Ipp8u pMask[3*3] = {1, 1, 1, 1, 0, 1, 1, 1, 1}; IppiSize maskSize = {3, 3}; Ipp16u pSrc[5*5] = { 1, 2, 4, 1, 2, 5, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 5, 1, 2}; Ipp16u pDst[5*5]; int srcStep = 5*sizeof(Ipp16u); int dstStep = 5*sizeof(Ipp16u); int dstSize = 5; IppStatus status = ippStsNoErr; int specSize = 0, bufferSize = 0; IppiBorderType borderType= ippBorderRepl; Ipp16u borderValue = 0; status = ippiMorphAdvGetSize_16u_C1R( roiSize, maskSize, &specSize, &bufferSize ); if (status != ippStsNoErr) return status; pSpec = (IppiMorphAdvState*)ippsMalloc_8u(specSize); pBuffer = (Ipp8u*)ippsMalloc_8u(bufferSize); status = ippiMorphAdvInit_16u_C1R( roiSize, pMask, maskSize, pSpec, pBuffer ); if (status != ippStsNoErr) { ippsFree(pBuffer); ippsFree(pSpec); return status; } status = ippiMorphCloseBorder_16u_C1R (pSrc, srcStep, pDst, dstStep, roiSize, borderType, borderValue, pSpec, pBuffer); ippsFree(pBuffer); ippsFree(pSpec); return status; }
The result is as follows:
pDst-> 5 4 4 2 2 5 4 4 2 2 2 2 2 2 2 2 2 5 2 2 2 2 2 2 2
