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. |
