AddProduct
Adds product of pixel values of two source images to floating-point pixel values of an accumulator image.
Syntax
Case 1: In-place operation
IppStatus ippiAddProduct_<mod>(const Ipp<srcDatatype>* pSrc1, int src1Step, const Ipp<srcDatatype>* pSrc2, int src2Step, Ipp32f* pSrcDst, int srcDstStep, IppiSize roiSize);
Supported values for mod:
8u32f_C1IR |
16u32f_C1IR |
32f_C1IR |
Case 2: Masked in-place operation
IppStatus ippiAddProduct_<mod>(const Ipp<srcDatatype>* pSrc1, int src1Step, const Ipp<srcDatatype>* pSrc2, int src2Step, const Ipp8u* pMask, int maskStep, Ipp32f* pSrcDst, int srcDstStep, IppiSize roiSize);

Parameters
pSrc1, pSrc2 |
Pointers to the source images ROI. |
src1Step, src2Step |
Distances in bytes between starts of consecutive lines in the source images. |
pMask |
Pointer to the mask image. |
maskStep |
Distance in bytes between starts of consecutive lines in the mask image. |
pSrcDst |
Pointer to the destination (accumulator) image ROI. |
srcDstStep |
Distance in bytes between starts of consecutive lines in the accumulator image. |
roiSize |
Size of the image ROI in pixels. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function adds the product of pixel values of two source images pSrc1 and pSrc2 to floating-point pixel values of the accumulator image pSrcDst as given by:
pSrcDst(x,y) = pSrcDst(x,y) + pSrc1(x,y) * pSrc2(x,y)
The products of pixel values in case of a masked operation are added only if the respective mask value is nonzero; otherwise, the accumulator pixel value remains unchanged.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when any of the specified pointers is null. |
ippStsSizeErr |
Indicates an error when roiSize.width or roiSize.height is negative. |
ippStsStepErr |
Indicates an error if src1Step, src2Step, maskStep, or srcDdstStep 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. |
