  2. Note that left and right are from the point of view of the object. See examples.
  3. Press the Submit Results button at the bottom once done.
  4. If you cannot localize a keypoint, leave it at its intial location. If you accidentally moved it, put it back in the black area. We will evalutate all the keypoints placed on the image.
  5. Press r or R if you need to reset the annotation.

Try to mark the shoulders and hip keypoints regardless of their visibility unless they fall outside the image

Shoulders, Elbows, Wrists, Hips, Knees, Ankles: Approximate limbs as cylinders. The joint location in 3D is the intersection of the axes of adjoining cylinders.

Nose Tip: The location is the tip of the nose, regardless of frontal or profile view.nose_frontal nose_profile

Eyes: In frontal view it is the midpoint of the two eye corners. The eye location does not depend on the pupils. frontal_eyes In profile view it is the tip of the eye surface.profile_eye Even if the eye is closed, we estimate the tip of the eye surface, ignoring the eyelids.

Ears: The tip of the tragus (the small pointed eminence of the external ear). frontal_ear. profile_ear

Shoulders, Elbows, Wrists, Hips, Knees, Feet: The clothes corresponding to the area of the joint do not hide the joint.visible_joint The joint may, however, be hidden by the torso or limbs of the same person. For example, in right profile view, the left joints of the body are often occluded by the torso and/or by the right limbs.
