Detailed Description

Filters the image using a high-pass 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 nppiFilterHighPassBorder 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).
eMaskSizeEnumeration value specifying the mask size.
eBorderTypeThe border type operation to be applied at source image border boundaries.
Returns
Image Data Related Error Codes, ROI Related Error Codes

\[ \left( \begin{array}{rrr} -1 & -1 & -1 \\ -1 & 8 & -1 \\ -1 & -1 & -1 \\ \end{array} \right) \left( \begin{array}{rrrrr} -1 & -1 & -1 & -1 & -1 \\ -1 & -1 & -1 & -1 & -1 \\ -1 & -1 & 24 & -1 & -1 \\ -1 & -1 & -1 & -1 & -1 \\ -1 & -1 & -1 & -1 & -1 \\ \end{array} \right) \]
