Humanoid motion tracking is central to teleoperation and whole-body imitation, yet evaluation often disagrees with what people perceive in videos. Kinematic errors average per-frame pose differences but miss the physical artifacts that matter most, particularly unstable support and incorrect contacts such as foot skating and mistimed touch-downs.

DirtyMoCap is a marker‑layout‑free framework that converts unordered, noisy optical motion capture markers into a fixed set of proxy anchors representing skeletal joints and body surface points. Using a recurrent sliding‑window architecture to track these anchors and a custom differentiable Gauss‑Newton solver to fit the SMPL‑H model, the method learns adaptive observation confidence, smoothness, and prior weights end‑to‑end. Experiments show that DirtyMoCap generalizes across arbitrary marker configurations, outperforms configuration‑specific baselines in joint and vertex accuracy, and achieves up to a 100× speedup over standard PyTorch implementations, enabling the creation of a temporally coherent Kung Fu motion dataset.

Pose-Anchored Optical Flow for Low-Latency Human Action Anticipation in Human-Robot Teaming proposes PoseOFF, a representation that captures local motion around human joints by conditioning optical flow extraction on pose. This structured motion representation aligns with human kinematics and improves early action recognition accuracy across multiple datasets and backbones. PoseOFF achieves comparable or better performance while observing less of the action sequence, making it suitable for real‑time, resource‑constrained robotic systems.
