Why It Matters
MotionBERT excels at capturing body orientation consistency, reducing the jitter that can destabilise blade trajectory reconstruction. Its masked sequence pretraining helps with occlusions caused by camerawork, boards, or other skaters.
Recommended Usage
- Deploy as a refinement stage after a fast detector such as RTMPose to balance throughput and accuracy.
- Extend the masked prediction objective with domain-specific augmentations (spin blurs, rink lighting) when adapting to figure skating footage.
- Export smoothed quaternions or Euler angles for downstream biomechanical analysis of spin centering and exit posture.
