nx_coco_ap.nx

nx_coco_ap.nx -- COCO keypoint AP@[.5:.95] from per-image OKS (the top-down single-person eval: GT box given, one prediction per image). AP = mean over the 10 OKS thresholds {.50,.55,...,.95} of the fraction of predictions whose OKS >= threshold. This is the number the field reports (ViTPose 75.8). Composes nx_coco_oks (per-image) -> this. The full COCO detection AP (P-R over confidence, multi-instance matching) is a superset; this is the standard keypoint-eval simplification used when the person box is provided (which is our top-down setting). license_tier: ORIGINAL
