As the title mentioned, considering to use opencv for next computer vision projects. As far as I know, Halide backend is slow,the opencl backend unless as good as cpu version, but dnn module of opencv3.4.2 only run on intel GPU.

This new project need to monitor many streams at the same time, a dedicated gpu of nvidia is the best choices for now.

Do the team of opencv has any plan to make opencl backend support gpu of nvidia/amd, or provide cuda backend in near future?

I believe OpenCL backend can work on other GPUs, it just have not been tested and tuned for them. Also, there are plans for Halide backend improvement.

@mshabunin, I tried with yolo v3, it switch back to cpu automatic, from the list of opencv4 route map, the only thing I could expect is Halide backend improvement

Yes, see the idea page for GSoC 2019. https://github.com/opencv/opencv/wiki... We have a very good mentor for this, we need good students.
