CompressMarkerLabelsGetBufferSize
Before calling any of the CompressMarkerLabels functions the application first needs to call the corresponding CompressMarkerLabelsGetBufferSize 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 CompressMarkerLabels function. NOTE: When compressing labels generated by the nppiLabelMarkersUF() functions the value of the nStartingNumber parameter below MUST be set to ROI width * ROI height.

CompressMarkerLabels
Renumber connected region marker label IDs from a previous call to nppiLabelMarkers 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. However, if you initially used nppiLabelMarkers_8u and the pNumber value returned by that function was over 255 then you will still have one or more disjoint connected regions with the same label ID in the final output from this function. Also, the output of nppiCompressMarkerLabels_32u8u will only produce correct results if the pNewNumber value returned by this function is less than 256. Before calling any of the CompressMarkerLabels functions the application first needs to call the corresponding CompressMarkerLabelsGetBufferSize 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 CompressMarkerLabels function. NOTE: When compressing labels generated by the nppiLabelMarkersUF() functions the value of the nStartingNumber parameter below MUST be set to ROI width * ROI height.
