Detailed Description

Dilation computes the output pixel as the maximum pixel value of the pixels under the mask.

Pixels who's corresponding mask values are zero do not participate in the maximum search.

It is the user's responsibility to avoid Sampling Beyond Image Boundaries.

Common parameters for nppiDilate functions include:

Parameters
pSrc Source-Image Pointer.
nSrcStep Source-Image Line Step.
pDst Destination-Image Pointer.
nDstStep Destination-Image Line Step.
oSizeROI Region-of-Interest (ROI).
pMask Pointer to the start address of the mask array
oMaskSize Width and Height mask array.
oAnchor X and Y offsets of the mask origin frame of reference w.r.t the source pixel.
nppStreamCtx Application Managed Stream Context.
Returns
Image Data Related Error Codes, ROI Related Error Codes
