Winning the AI Challenger Human Pose Keypoint Contest with Multi‑Scale Fusion

The Firefly team secured first place in the AI Challenger human skeletal keypoint detection contest by employing a top‑down approach that combines Faster R‑CNN for person detection, a multi‑scale region‑feature fusion strategy, varied Gaussian and binary supervision, OKS‑NMS post‑processing, and extensive experiments demonstrating the impact of input size, supervision radius, and model stacking.
