Detailed Description

Computes the average pixel values of the pixels under a rectangular mask with border control.

If any portion of the mask overlaps the source image boundary the requested border type operation is applied to all mask pixels which fall outside of the source image. These versions of the functions are intended to significantly improve performance when very large mask sizes are used.

Currently only the NPP_BORDER_REPLICATE border type operation is supported. *

Common parameters for nppiFilterBoxBorderAdvanced functions include:

Parameters
pSrcSource-Image Pointer.
nSrcStepSource-Image Line Step.
oSrcSizeSource image width and height in pixels relative to pSrc.
oSrcOffsetThe pixel offset that pSrc points to relative to the origin of the source image.
pDstDestination-Image Pointer.
nDstStepDestination-Image Line Step.
oSizeROIRegion-of-Interest (ROI).
oMaskSizeWidth and Height of the neighborhood region for the local Avg operation.
oAnchorX and Y offsets of the kernel origin frame of reference relative to the source pixel.
eBorderTypeThe border type operation to be applied at source image border boundaries.
pBufferPointer to device memory buffer of size hpBufferSize bytes returned by calling nppiFilterBoxBorderAdvancedGetDeviceBufferSize.
nppStreamCtxApplication Managed Stream Context.
Returns
Image Data Related Error Codes, ROI Related Error Codes
