Highlights
- Utilises detector-guided keyframe selection to focus computation on peak airtime and landing frames.
- Trained jointly on jump type and spin family labels, improving recognition of visually similar elements.
- Provides calibrated confidence scores that downstream judging heuristics can threshold.
Implementation Notes
Augmentations emphasise slow shutter artifacts common in rink footage; replicate them when adapting to new broadcasts. Pairing Keyframe-TSN with a lightweight pose estimator improves false negative rates on layback spins.
