Using Streams with functions like meanStdDev?

edit

What about for functions minMax and GpuMat::setTo, they dont have function overloads that take streams either?

I have a set of processing that I have running on images that include these non streamable functions. If I create a stream per thread and try to process multiple image at the same time (say one per thread, passing the thread's associated stream to the cuda opencv functions that take one), i seem to be getting a crash when i get to a function (like cv::cuda::minMax) that doesnt have an overload that accepts a stream, is that expected?

I need to use reduction operations like minMax in my pipeline, is there any way to have an image processing pipeline where one could use such functions that can run concurrently?

Thanks, Ryan

Which version of OpenCV are you using? meanStdDev takes cuda streams, although from what I have said above this will not work correctly if you are issuing commands from multiple threads to different streams because it uses npp. You can test it on your system by running

opencv_test_cudaarithm.exe" --gtest_filter=CUDA_Arithm/MeanStdDev.Async/0

minMax also takes streams but the function is called findMinMax, you can test with

opencv_test_cudaarithm.exe" --gtest_filter=CUDA_Arithm/MinMaxLoc.Async/0
