Keypoint & Landmark Annotation

Marking specific points such as joints, facial features or product corners, so a model can learn pose, shape and alignment rather than just where an object is.

What to send us

The images, the keypoint schema with the order and name of each point, and how to handle points that are hidden, out of frame or ambiguous. A reference diagram of the skeleton or landmarks is essential.

What you get back

Keypoint coordinates with a visibility flag per point, in COCO keypoints or your own format, with left and right points labeled consistently from the subject's point of view.

What to check before you sign off

Check that left and right were not swapped on subjects facing the camera, the most common keypoint error. Confirm hidden points are flagged rather than guessed.
