Overview of the recording setup (a) and its output (b) and (c). The cameras recording the infants are circled in red. For this study, only the two cameras labeled diagonal/top view were used. Panels (b) and (c) show example frames for infants of different age and pose complexity from the two different views. The extracted pose keypoints are displayed as skeletons over the image. Note that neither the human annotators nor any of the pose estimators could reliably determine the position of the fully covered ear in the rightmost example.
