What is Keypoint Annotation?
Keypoint annotation involves marking specific points of interest on objects—like joints on a human body, features on a face, or anatomical landmarks. Each point is precisely positioned with sub-pixel accuracy.
Essential for pose estimation (17 body points), facial recognition (68 facial landmarks), hand tracking (21 hand points), and medical imaging (custom anatomical points).
