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 isNULL.
- ippStsSizeErr
- Indicates an error whenroiSize.widthorroiSize.heightis negative.
- ippStsStepErr
- Indicates an error whensrcStep,maskStep, orsrcDstStepis less thanroiSize.width * <pixelSize>.
- ippStsNotEvenStepErr
- Indicates an error condition if one of step values for floating-point images cannot be divided by 4.
