The OpenPose papers describe multi-person 2D pose estimation, including bottom-up association of parts and top-down detection failure when nearby people are missed. Image-plane keypoints do not establish 3D depth or medical status.
Jin Dive
The original OpenPose paper presents a bottom-up system that jointly predicts confidence maps for body-part locations and Part Affinity Fields (PAFs) for associations. Its parser uses PAF scores in bipartite matching to assemble candidate parts into person-specific poses. The paper notes that a top-down pipeline can miss people close together; downstream pose estimation cannot recover a missed detection. The later OpenPose paper describes body, foot, hand and facial keypoints. These are image-plane outputs, not clinical measures or 3D coordinates.

Evaluate keypoint estimation under the target conditions, including crowding, occlusion and camera variation. Any use beyond image-plane pose estimation requires additional evidence and task-specific validation.

What does OpenPose predict to estimate body-part locations?
OpenPose’s network predicts confidence maps for body-part locations, alongside Part Affinity Fields used to associate body parts.
What step does the OpenPose parser use to associate candidate body parts into full poses?
The paper describes a parser that performs bipartite matching using PAF scores, then assembles body-part candidates into full poses.
What failure mode of top-down pose estimation does the OpenPose paper discuss in crowded scenes?
The paper notes that top-down pipelines can miss people in close proximity; a downstream pose estimator cannot recover a person whose detection was missed.
