The exact meaning of the return value depends on the threading framework used by OpenCV library:
TBB
- Unsupported with current 4.1 TBB release. Maybe will be supported in future.OpenMP
- The thread number, within the current team, of the calling thread.Concurrency
- An ID for the virtual processor that the current context is executing on (0 for master thread and unique number for others, but not necessary 1,2,3,...).GCD
- System calling thread's ID. Never returns 0 inside parallel region.C=
- The index of the current parallel task.
