AbsDiff
Calculates absolute difference between two images.
Syntax
IppStatus ippiAbsDiff_<mod>(const Ipp<datatype>* pSrc1, int src1Step, const Ipp<datatype>* pSrc2, int src2Step, Ipp<datatype>* pDst, int dstStep, IppiSize roiSize);
Supported values for mod:
8u_C1R |
16u_C1R |

Parameters
pSrc1 |
Pointer to the first source image. |
src1Step |
Distance in bytes between starts of consecutive lines in the first source image. |
pSrc2 |
Pointer to second source image. |
src2Step |
Distance in bytes between starts of consecutive lines in the second 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. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function calculates the absolute pixel-wise difference between two images by the formula:
pDst(x,y) = abs(pSrc1(x,y) - pSrc2(x,y)).
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 src1Step, src2Step 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. |
