openCV with GPU

[shivajid]

I was looking to use OpenCV with Cuda8. I have Cuda8, but have not been successful with getting openCV working with it. Is there any guidelines for that?

You have to install Cuda Tookit 8 first (which I assume you have) and compile OpenCV with at least these flags
-D WITH_CUDA=ON
-D ENABLE_FAST_MATH=1
-D CUDA_FAST_MATH=1
-D WITH_CUBLAS=1

After you run cmake, you should get in the ouput that NVIDIA CUDA is enabled.

Thanks nachomartinr. I tried the above steps and had some issues with OpenCV, thus raised the issue. I was wondering if you can point me to the openCV version that you have have tried out.

I have a GPU enabled OpenCV 3.1 installed in my computer, but compiled from sources. I had problems compiling it, but they weren't related to CUDA, but to the GCC version (OpenCV does not support GCC 6 yet). I don't know of any binary release with enabled GPU acceleration.
