Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib

Parameters

pSrc

Pointer to the source image ROI.

srcStep

Distance in bytes between the starting points of consecutive lines in the source image.

pDst

Pointer to the destination image ROI.

dstStep

Distance in bytes between the starting points of consecutive lines in the destination image.

roiSize

Size of the destination ROI in pixels.

maskSize

Size of the mask in pixels.

BorderType

Type of border. Possible values are:

ippBorderConst

Values of all border pixels are set to constant.

ippBoderRepl

Border is replicated from the edge pixels.

ippBorderInMem

Border is obtained from the source image pixels in memory.

ippBorderMirror

Border pixels are mirrored from the source image boundary pixels.

Mixed borders are also supported. They can be obtained by the bitwise operation OR between any of the ippBorderRepl, ippBorderConst, ippBorderMirror, and the ippBorderInMemTop, ippBorderInMemBottom, ippBorderInMemLeft, ippBorderInMemRight values.

borderValue

Constant value to assign to border pixels. This parameter is applicable only to the ippBorderConst border type.

pBuffer

Pointer to the work buffer.

Description

Before using this function, you need to compute the size of the work buffer pBuffer using the SumWindowGetBufferSize function.

This function operates with ROI (see Regions of Interest in Intel IPP).

This function sets each pixel in the destination image ROI pDst to the sum of all the source image pixels in the rectangular neighborhood of size maskSize with the anchor cell at the corresponding pixel in the source image ROI pSrc. To ensure valid operation while processing the image boundary pixels, the application must correctly define additional border pixels (see Borders in Neighborhood Operations).

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error or a warning.

ippStsNullPtrErr

Indicates an error if pSrc or pDst is NULL.

ippStsSizeErr

Indicates an error if roiSize has a field with a zero or negative value.

ippStsMaskSizeErr

Indicates an error if maskSize has a field with a zero or negative value.

ippStsBorderErr

Indicates an error if BorderType has an illegal value.
