A lying-on-the-ground detector trained only on synthetic CCTV images, tested on real footage from two homes
We trained D-FINE, RF-DETR and YOLO on our 1,000-image Fall dataset and nothing else, then scored them on two public real-footage sets. The synthetic-only D-FINE Small catches 97% of people on the floor at 5% false alarms; the model trained on real footage from one room catches 24% of falls in another home.
- 97.4%
- lying frames caught at 5% false alarms (real footage)
- 24% → 83–87%
- falls caught in a new home: real-only vs synthetic-only
