So I am from Team 3501. This summer/year we're going to attempt using OpenCV for our vision code and develop better coding skills to use its library to our purposes.
Here's a youtube video of me showing how to install it on a mac with the java capability through the .jar and hooking it into Eclipse.
I don't have a windows, im sorry. there's probably an easier way, or a very similar process in that you need to follow the steps.
All the links are provided in the video's description hope you all like it. Go Robotics!
