WebFeb 4, 2024 · To prevent creating subthreads we executed function cv::setNumThreads(0). We faced with performance degrading with increasing number of processing threads. So we cannot achieve increased performance in multithreading application due to some locks. A similar problem is observed with some other functions (cv::bilateralFilter and cv::integral). monarch tools
