Hi, I have made my own package of opencv 3.2 with CUDA 8.0 and I run it with Microsoft Visual studio 2015 but when I tried with https://devblogs.nvidia.com/parallelf... my time with GPU are more slower than CPU. I built it in x64 and debug mode, I have an error with <<< for the kernel but the program compil and run

Do you have any idea ?

Thanks
