Detailed Description

Filters the image using a Laplacian filter kernel 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 nppiFilterLaplaceBorder functions include:

Parameters

pSrc	Source-Image Pointer.
nSrcStep	Source-Image Line Step.
oSrcSize	Source image width and height in pixels relative to pSrc.
oSrcOffset	The pixel offset that pSrc points to relative to the origin of the source image.
pDst	Destination-Image Pointer.
nDstStep	Destination-Image Line Step.
oSizeROI	Region-of-Interest (ROI).
eMaskSize	Enumeration value specifying the mask size.
eBorderType	The border type operation to be applied at source image border boundaries.

Returns: Image Data Related Error Codes, ROI Related Error Codes

$\left( \begin{array}{rrr} -1 & -1 & -1 \\ -1 & 8 & -1 \\ -1 & -1 & -1 \\ \end{array} \right) \left( \begin{array}{rrrrr} -1 & -3 & -4 & -3 & -1 \\ -3 & 0 & 6 & 0 & -3 \\ -4 & 6 & 20 & 6 & -4 \\ -3 & 0 & 6 & 0 & -3 \\ -1 & -3 & -4 & -3 & -1 \\ \end{array} \right)$
