@LiuPeiqiCN Thanks for the issue report. Several notes on the code:
- Nested parallel_for does not make sense.
- OpenMP uses own thread pool and scheduler. Mix of OpenCV (Concurrency by default) parallel framework and OpenMP may produce collisions and dead locks. At least you'll get 2 concurrent thread pools.
I propose to get rid of nested parallelism and OpenMP and recheck result.
