I use
Device 0: "GeForce 820M" 2048Mb, sm_21, 96 cores, Driver/Runtime ver.7.0/7.0
Run Cuda 7.0
OpenCV 2.4.9 compiled with CUDA
OS : Ubuntu 14.04
Now I am tried compiling an example from online http://www.robesafe.com/personal/pablo.alcantarilla/code/cuda_flow_1_0.tar.gz
And I compiled it as instructions provided by the ReadMe. File and now when i run ./farneback .video
I get this output with error :
