Rock, Paper, Scissor, Computer Vision, ML!

Mind the Geek

The goal of this session is to leverage computer vision, machine learning and Java to modernize the casual 'Rock, Paper, Scissor' game. It starts with a (gentle) introduction to computer vision. Those newly learned skills will then be used to implement the necessary hand gesture recognition with OpenCV. The presentation concludes by spicing up the game to contrast and compare computer vision with machine learning. What are the benefits (and limitations) of CV vs. ML? Can CV complements ML? And don’t worry, even though computer vision and machine learning are sometimes very academic topics, this session will be fun and very hands-on....literally!
