3D Human Pose Estimation via Intuitive Physics

Figure 1 . Estimating a 3D body from an image is ill-posed. A recent, representative, optimization method [59] produces bodies that are in unstable poses, penetrate the floor, or hover above it. In contrast, IPMAN estimates a 3D body that is physically plausible. To achieve this, IPMAN uses novel intuitive-physics (IP) terms that exploit inferred pressure heatmaps on the body, the Center of Pressure (CoP), and the body's Center of Mass (CoM). Body heatmap colors encode per-vertex pressure.
