The Game
POLYPedia, established in 2022, is a polyp detection game for learning to spot colorectal polyps in endoscopic images. Detection Mode has 8 modules of 200 images. In each image your job is to find the polyp, or recognize that there isn't one, quickly and accurately. Every answer is timed, scored and reviewed, and signed-in players are ranked on a leaderboard for each module.
How to play is shown on the Before You Start screen when you open a module or the tutorial.
