Our project, Radminton (or Decision Support in Racket Games) is a training and learning tool for players of badminton, with other racket sports planned to be added in the future. Radminton uses computer vision to analyze user uploaded videos of their badminton games and generate feedback for the user on how they could improve. Through an easy-to-use website, Radminton makes it easy for players of all skill levels to get feedback on their badminton games.
