FilterBox
Blurs an image using a simple box filter.
Syntax
IppStatus ippiFilterBox_64f_C1R(const Ipp<datatype>* pSrc, int srcStep, Ipp<datatype>* pDst, int dstStep, IppiSize dstRoiSize, IppiSize maskSize, IppiPoint anchor);

Parameters
pSrc |
Pointer to the source image ROI. |
srcStep |
Distance in bytes between starts of consecutive lines in the source image. |
pDst |
Pointer to the destination image ROI. |
dstStep |
Distance in bytes between starts of consecutive lines in the destination image. |
dstRoiSize |
Size of the destination ROI in pixels. |
maskSize |
Size of the mask in pixels. |
anchor |
Anchor cell specifying the mask alignment with respect to the position of the input pixel. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function sets each pixel in the destination image as the average of all the input image pixels in the rectangular neighborhood of size maskSize with the anchor cell at that pixel. This has the effect of smoothing or blurring on the input image. To ensure valid operation when image boundary pixels are processed, 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, pDst, or pSrcDst is NULL. |
ippStsSizeErr |
Indicates an error if dstRoiSize has a field with zero or negative value. |
ippStsStepErr |
Indicates an error if srcStep or dstStep has a zero or negative value. |
ippStsMaskSizeErr |
Indicates an error if maskSize has a field with zero or negative value. |
ippStsAnchorErr |
Indicates an error if anchor is outside the mask size. |
ippStsMemAllocErr |
Indicates a memory allocation error. |
