public static class nppif.NppiBufferDescriptor
extends Pointer

\name CompressMarkerLabelsUFBatch Renumber connected region marker label IDs from one or more previous calls to nppiLabelMarkersUF_32u_C1R(_Ctx), nppiLabelMarkersUFBatch_32u_C1R(_Ctx), or nppiLabelMarkersUFBatch_32u_C1R_Advanced(_Ctx) calls to eliminate label numbering sparseness. Note that while marker label IDs still start at ID number 1, the value of pNewNumber returned by this function will represent the minimum number of label IDs to give each connected region in the image a unique label ID. Before calling any of the CompressMarkerLabelsUFBatch functions the application first needs to call the corresponding CompressMarkerLabelsGetBufferSize to determine the amount of device memory to allocate as a working buffer for each image. If all of the images in the batch have the same ROI values then the total amount of device memory needed is the value returned by CompressMarkerLabelsGetBufferSize and can be allocated as a single chunk of device memory of returned buffer size value * nBatchList or separately per image in the batch. The pointer to each buffer if the images in the batch have variable ROIs is the returned buffer size for each image. This can also be allocated as a single chunk of device memory for all images in the list if desired. In any case, the buffer pointers for each image in the batch list must be set correctly per each image. Once pBufferList is created and initialized then it needs to be copied to device memory and a pointer to that list must be passed to the compression batch function. Note that these functions are only supported for output from the UF versions of LabelMarkers functions. Also, for each marker labels image in the list the same image pointer value and ROI that were used when creating the marker labels image MUST be used. Also note that the images in this function must be allocated with cudaMalloc() and NOT cudaMallocPitch(). And the pitch MUST be set to oSize.width * sizeof(Npp32u). And the image pointers and oSize values MUST match those used when the nppiLabelMarkersUF funcions were called. \{
