Detailed Description

Erosion using a 3x3 mask with the anchor at its center pixel 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.

Currently only the NPP_BORDER_REPLICATE border type operation is supported.

Common parameters for nppiErode3x3Border functions include:

Parameters
pSrc Source-Image Pointer.
nSrcStep Source-Image Line Step.
oSrcSize Source image width and height in pixels relative to pSrc.
oSrcOffset Source image starting point relative to pSrc.
pDst Destination-Image Pointer.
nDstStep Destination-Image Line Step.
oSizeROI Region-of-Interest (ROI).
eBorderType The border type operation to be applied at source image border boundaries.
nppStreamCtx Application Managed Stream Context.
Returns
Image Data Related Error Codes, ROI Related Error Codes
