Detailed Description

Erosion followed by Dilation with border control.

Morphological open computes the output pixel as the minimum pixel value of the pixels under the mask followed by a second pass using the result of the first pass as input which outputs the maximum pixel value of the pixels under the same mask. Pixels who's corresponding mask values are zero do not participate in the minimum or maximum search.

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. The mask is centered over the source image pixel being tested.

Before calling any of the MorphOpenBorder functions the application first needs to call the corresponding MorphGetBufferSize to determine the amount of device memory to allocate as a working buffer. The allocated device memory is then passed as the pBuffer parameter to the corresponding MorphOpenBorder function.

Use the oSrcOffset and oSrcSize parameters to control where the border control operation is applied to the source image ROI borders.

Currently only the NPP_BORDER_REPLICATE border type operation is supported.

Common parameters for nppiMorphOpenBorder functions include:

Parameters
pSrcSource-Image Pointer.
nSrcStepSource-Image Line Step.
oSrcSizeSource image width and height in pixels relative to pSrc.
oSrcOffsetSource image starting point relative to pSrc.
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.
pBufferPointer to device memory scratch buffer at least as large as value returned by the corresponding MorphGetBufferSize call.
eBorderTypeThe border type operation to be applied at source image border boundaries.
nppStreamCtxApplication Managed Stream Context.
Returns
Image Data Related Error Codes, ROI Related Error Codes
