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
).
