AddSquare
Adds squared pixel values of a source image to floating-point pixel values of an accumulator image.
Syntax
Case 1: In-place operation
IppStatus ippiAddSquare_<mod>(const Ipp<srcDatatype>* pSrc, int srcStep, Ipp32f* pSrcDst, int srcDstStep, IppiSize roiSize);
Supported values for mod:
8u32f_C1IR |
16u32f_C1IR |
32f_C1IR |
Case 2: Masked in-place operation
IppStatus ippiAddSquare_<mod>(const Ipp<srcDatatype>* pSrc, int srcStep, const Ipp8u* pMask, int maskStep, Ipp32f* pSrcDst, int srcDstStep, IppiSize roiSize);
Supported values for mod:
8u32f_C1IMR |

Parameters
pSrc |
Pointer to the source image ROI. |
srcStep |
Distance in bytes between starts of consecutive lines in the source image. |
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 squared pixel values of the source image pSrc to floating-point pixel values of the accumulator image pSrcDst as follows:
pSrcDst(x,y) = pSrcDst(x,y) + pSrc(x,y)2
Addition of the squared pixel values in case of a masked operation is performed only if the respective mask value is nonzero; otherwise, the accumulator pixel value remains unchanged.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or a warning. |
ippStsNullPtrErr |
Indicates an error condition if any of the specified pointers is NULL. |
ippStsSizeErr |
Indicates an error when roiSize.width or roiSize.height is negative. |
ippStsStepErr |
Indicates an error when srcStep, maskStep, or srcDstStep 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. |
