Dear experts, I have few questions about compiling for GPU to get better performance: 1- When I compile for GPU, does it work then on all GPUs or only Cuda Geforce? 2- If the application run on a PC which dont have GPU, does it run? 3- Any straight forward tutorial for this? Thanks

You can find something for opencv 2.4.11

For opencv 3.0 I don't know where you can find docs

In opencv 3.0 doc is here I think if you explicit Cuda function Gpu. I'm not an expert in GPU but I think that as all functions are in namespace cv::CUDA and hence if you haven't got GPU you will run in an exception
