Cv2GetNumThreads Method

Returns the number of threads used by OpenCV for parallel regions. Always returns 1 if OpenCV is built without threading support. The exact meaning of return value depends on the threading framework used by OpenCV library: - `TBB` - The number of threads, that OpenCV will try to use for parallel regions. If there is any tbb::thread_scheduler_init in user code conflicting with OpenCV, then function returns default number of threads used by TBB library. - `OpenMP` - An upper bound on the number of threads that could be used to form a new team. - `Concurrency` - The number of threads, that OpenCV will try to use for parallel regions. - `GCD` - Unsupported; returns the GCD thread pool limit(512) for compatibility. - `C=` - The number of threads, that OpenCV will try to use for parallel regions, if before called setNumThreads with threads > 0, otherwise returns the number of logical CPUs, available for the process.
