A stitching with CUDA did not work.

<enviroment> OpenCV4.1.1, OpenCV_Contribute4.1.1, CUDA10.1, TBB20190605, VisualStudio2019 , Cmake 3.14.1, Corei7 8700, GTX 1070Ti

OpenCV-reference said: "If you have cuda device cv::Stitcher can be configured to offload certain operations to GPU. If you prefer this configuration set try_use_gpu to true." link : https://docs.opencv.org/master/d8/d19...

But there isn't "try-use-gpu" in the sample code. Thank you in advance.

I don't thnk that's possible using stitcher class (something is wrong in doc). If you want to use CUDA for stitching you must compile opencv with CUDA and use stitching_detailed.cpp or stitching_detailed.py

The flag name was changed to --try_cuda (yes|no) in the detailed example. But the idea is still the same as what author is looking for.

Thank you very much for your quick response. I see that there are probably something wrong in the doc. I will try using stitching_detailed.cpp. thx
