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

LabelMarkers
Generate image connected region label markers to be used for later image segmentation. A connected region is any non-zero pixel region bounded by pixel values less than or equal to nMinVal. Pixels outside the ROI are always treated as having values of 0 thus resulting in a connected region segmentation boundary in that direction. Note that while marker label IDs start at ID number 1, they are not generated in any particular order and there may be numeric gaps between sequential marker IDs. The pNumber parameter returns the value of the maximum label ID generated in the first pass. However during convergence passes higher label ID numbers in connected regions containing multiple label ID numbers will be replaced with the lowest label ID number in the region. However, connected region label IDs will be unique unless the value returned by pNumber exceeds the data type range of a destination pixel in which case ID values will roll over causing some to be used on multiple connected regions. If this occurs for 8 bit data it is recommended that you use the 8u32u version of the function for 8 bit data. Pixels not connected to any connected region like those with values less than or equal to nMinVal will be assigned a marker label ID value of 0. Before calling any of the LabelMarkers functions the application first needs to call the corresponding LabelMarkersGetBufferSize 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 LabelMarkers function.

LabelMarkersUF
Generate image connected region label markers to be used for later image segmentation. A connected region is any pixel region where all pixels in the region have the same pixel value. Note that marker label IDs generally increase in value from image left to right and top to bottom they are not generated in any particular order and there may be numeric gaps between sequential marker IDs. To limit the number of marker IDs generated the application should pass the image through a threshold filter before calling this funcion. Doing so however does not necessarily limit the maximum marker ID value generated by this function. Note that these functions currently only support image ROI sizes up to 4 gigapixels. Also note that while these functions support destination image pitches that are not exactly equal to oSizeROI.width * sizeof(Npp32u) it can avoid a cudaMemCpyAsync() call to copy the final result from the working buffer to the destination image if the pitch exactly equals oSizeROI.width * sizeof(Npp32u). Before calling any of the LabelMarkersUF functions the application first needs to call the LabelMarkersUFGetBufferSize 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 LabelMarkersUF function. The algorithm used in this implementation is based on the one described in "An Optimized Union-Find Algorithm for Connected Components Labeling Using GPUs" by Jun Chen and others. Note that the destination image in these functions must be allocated with cudaMalloc() and NOT cudaMallocPitch(). Also the pitch of the output image MUST be set to oSizeROI.width * sizeof(Npp32u).

LabelMarkersUFBatch
Generate image connected region label markers to be used for later image segmentation for a batched list of images. A connected region is any pixel region where all pixels in the region have the same pixel value. Note that marker label IDs generally increase in value from image left to right and top to bottom they are not generated in any particular order and there may be numeric gaps between sequential marker IDs. To limit the number of marker IDs generated the application should pass the image through a threshold filter before calling this funcion. Doing so however does not necessarily limit the maximum marker ID value generated by this function. Note that these functions currently only support image ROI sizes up to 4 gigapixels. Also note that these functions work directly in the destination image so destination pitch MUST be equal to destination ROI.width * sizeof(Npp32u) and even if destination pitch is greater than that the output will be in that format. If this doesn't work for you use the single image version of these functions or cudaMemCopy2D can be called for each output image to restore the original pitch. Note that all source and destination images in the batch list must contain enough device memory to support the full ROI size. ROIs in descriptor lists are ignored in these functions. The algorithm used in this implementation is based on the one described in "An Optimized Union-Find Algorithm for Connected Components Labeling Using GPUs" by Jun Chen and others. Note that the destination images in these functions must be allocated with cudaMalloc() and NOT cudaMallocPitch(). Also the pitch of the output image MUST be set to oSizeROI.width * sizeof(Npp32u).

pSrcBatchList	Source-Batch-Images Pointer device memory pointer to the list of device memory source image descriptors, oSize element is ignored.
pDstBatchList	Destination-Batch-Images Pointer device memory pointer to the list of device memory destination image descriptors, oSize element is ignored.
nBatchSize	Number of NppiImageDescriptor structures processed in this call (must be > 1).
oSizeROI	Region-of-Interest (ROI).
eNorm	Type of pixel connectivity test to use, nppiNormInf will use 8 way connectivity and nppiNormL1 will use 4 way connectivity for all images in batch.
nppStreamCtx	Application Managed Stream Context.

Returns
