Do you mean something like this https://devblogs.nvidia.com/parallelf... I'm sorry I don't have any experience with CUDA

Hello to everyone,

I'm trying to run OpenCVs calcOpticalFlowPyrLK on my GPU. I'm using Visual Studio 2012 and OpenCL 2.4.10 because OpenCV 3.0 doesn't work fine. I tried it one one PC with a AMD Radeon and also on a Laptop with an NVIDIA Geforce.

At first i tried it with OpenCL. Included this: #include "<"opencv2\ocl\ocl.hpp">" When I try to declare the oclMat Variable and scroll the mouse over it, it says: computes element-wise minimum of the two arrays (dst=min(src1,src2))

It also says: ";" expected when i scroll over the name I wanted to give my oclMat Object.

Then I tried everything with CUDA and it was nearly the same.

Does someone have an idea? Which Versions of what do I have to install?

Thank you for your help! PS: Sorry for the bad formatting
