anomaly_region_overlap — SPC anomaly_eval op

• データ種: video × video → table

• 呼び出し: import fullseye as fs; fs.ledger.anomaly_region_overlap(predicted, masks, min_overlap=0.5) (実装を直接呼ぶなら import anomeval; anomeval.anomaly_region_overlap(predicted, masks, min_overlap=0.5)、台帳から引くなら opsspc.get("anomaly_region_overlap"))

使い方

Per-region overlap of a binary defect prediction with the ground-truth regions at one operating point (table).

predicted and masks are binary (n, H, W) (or 2-D). For every 8-connected ground-truth region C: overlap = |predicted ∩ C| / |C|; a region counts as detected when overlap >= min_overlap. Returns overlap (per region, in mask order), pro (their mean = one point of the PRO curve), detected_fraction, hit_any (fraction of regions touched by at least one predicted pixel), fpr (predicted good pixels / good pixels), n_regions, min_overlap.

Raises ValueError on empty / mismatched / non-binary input, no ground-truth region, or min_overlap outside (0, 1].
