AbsDiffC
Calculates absolute difference between image and scalar value.
Syntax
IppStatus ippiAbsDiffC_<mod>(const Ipp<datatype>* pSrc, int srcStep, Ipp<datatype>* pDst, int dstStep, IppiSize roiSize, int value);
Supported values for mod:
8u_C1R |
16u_C1R |
IppStatus ippiAbsDiffC_32f_C1R(const Ipp32f* pSrc, int srcStep, Ipp32f* pDst, int dstStep, IppiSize roiSize, Ipp32f value);

Parameters
pSrc |
Pointer to the source image. |
srcStep |
Distance in bytes between starts of consecutive lines in the source image. |
pDst |
Pointer to the destination image. |
dstStep |
Distance in bytes between starts of consecutive lines in the destination image. |
roiSize |
Size of the image ROI in pixels. |
value |
Scalar value used to decrement each element of the source image. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function calculates the absolute pixel-wise difference between the source image pSrc and the scalar value by the formula:
pDst(x,y) = abs(pSrc(x,y) - value.
The function clips the value to the range [0, 255] for the 8u data type, and to the range [0, 65535] for the 16u data type.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error condition if one of the specified pointers is NULL. |
ippStsSizeErr |
Indicates an error condition if roiSize has a field with zero or negative value. |
ippStsStepErr |
Indicates an error when srcStep or dstStep is less than roiSize.width * <pixelSize>. |
ippStsNotEvenStepErr |
Indicates an error condition if one of step values for floating-point images cannot be divided by 4. |
