AddSquare

Syntax

Parameters

pSrc1	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

The function ippiAddSquare is declared in the ippcv.h file. It 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.
