Image Morphological Operations

Morphological image operations.

Morphological operations are classified as Neighborhood Operations.

These functions can be found in the nppim library. Linking to only the sub-libraries that you use can significantly save link time, application load time, and CUDA runtime startup time when using dynamic libraries.

Image Dilate Border

Dilation with border control

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. For gray scale dilation the mask contains signed mask values which are added to the corresponding source image sample value before determining the maximun value after clamping.

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 nppiDilateBorder functions:

param pSrc: Source-Image Pointer.
param nSrcStep: Source-Image Line Step.
param oSrcSize: Source image width and height in pixels relative to pSrc.
param oSrcOffset: Source image starting point relative to pSrc.
param pDst: Destination-Image Pointer.
param nDstStep: Destination-Image Line Step.
param oSizeROI: Region-Of-Interest (ROI).
param pMask: Pointer to the start address of the mask array
param oMaskSize: Width and Height mask array.
param oAnchor: X and Y offsets of the mask origin frame of reference w.r.t the source pixel.
param eBorderType: The border type operation to be applied at source image border boundaries.
param nppStreamCtx: Application Managed Stream Context.
return: Image Data Related Error Codes, ROI Related Error Codes

Image Erode Border

Erosion with border control

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 minimum search. For gray scale erosion the mask contains signed mask values which are added to the corresponding source image sample value before determining the minimum value after clamping.

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 nppiErodeBorder functions:

param pSrc: Source-Image Pointer.
param nSrcStep: Source-Image Line Step.
param oSrcSize: Source image width and height in pixels relative to pSrc.
param oSrcOffset: Source image starting point relative to pSrc.
param pDst: Destination-Image Pointer.
param nDstStep: Destination-Image Line Step.
param oSizeROI: Region-Of-Interest (ROI).
param pMask: Pointer to the start address of the mask array
param oMaskSize: Width and Height mask array.
param oAnchor: X and Y offsets of the mask origin frame of reference w.r.t the source pixel.
param eBorderType: The border type operation to be applied at source image border boundaries.
param nppStreamCtx: Application Managed Stream Context.

Image Morph Close Border

MorphCloseBorder

Dilation followed by Erosion with border control.

Morphological close computes the output pixel as the maximum 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 minimum pixel value of the pixels under the same mask. Pixels who’s corresponding mask values are zero do not participate in the maximum or minimum 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 MorphCloseBorder 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 MorphCloseBorder 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.

Image Morph Top Hat Border

MorphToHatBorder

Source pixel minus the morphological open pixel result with border control.

Morphological top hat computes the output pixel as the source pixel minus the morphological open result of the pixels under the mask. Pixels who’s corresponding mask values are zero do not participate in the maximum or minimum 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 MorphTopHatBorder 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 MorphTopHatBorder 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 nppiMorphTopHatBorder functions:

param pSrc: Source-Image Pointer.
param nSrcStep: Source-Image Line Step.
param oSrcSize: Source image width and height in pixels relative to pSrc.
param oSrcOffset: Source image starting point relative to pSrc.

param nDstStep: Destination-Image Line Step.
param oSizeROI: Region-Of-Interest (ROI).
param pMask: Pointer to the start address of the mask array
param oMaskSize: Width and Height mask array.
param oAnchor: X and Y offsets of the mask origin frame of reference w.r.t the source pixel.
param pBuffer: Pointer to device memory scratch buffer at least as large as value returned by the corresponding MorphGetBufferSize call.
param eBorderType: The border type operation to be applied at source image border boundaries.
param nppStreamCtx: Application Managed Stream Context.
