Detailed Description

Erosion computes the output pixel as the minimum 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 nppiErode functions include:

Parameters
pSrcSource-Image Pointer.
nSrcStepSource-Image Line Step.
pDstDestination-Image Pointer.
nDstStepDestination-Image Line Step.
oSizeROIRegion-of-Interest (ROI).
pMaskPointer to the start address of the mask array
oMaskSizeWidth and Height mask array.
oAnchorX and Y offsets of the mask origin frame of reference w.r.t the source pixel.
nppStreamCtxApplication Managed Stream Context.
Returns
Image Data Related Error Codes, ROI Related Error Codes
