anomaly_pro — SPC anomaly_eval op

• データ種: video × video → table
• 呼び出し: import fullseye as fs; fs.ledger.anomaly_pro(scores, masks, fpr_max=0.3) (実装を直接呼ぶなら import anomeval; anomeval.anomaly_pro(scores, masks, fpr_max=0.3)、台帳から引くなら opsspc.get("anomaly_pro"))

使い方

Per-region overlap (PRO) curve and its normalised area AUPRO up to fpr_max (table).

Definition (Bergmann et al., CVPR 2020): at a threshold t, every 8-connected defect region C of every mask scores |{score >= t} ∩ C| / |C|; PRO(t) is the mean over all regions, so a small defect weighs as much as a large one. FPR(t) is the fraction of all good pixels with score >= t. The curve is evaluated exactly at every distinct score (sorted cumulative sums, no threshold grid), starts at (0, 0), is integrated by the trapezoid rule up to fpr_max (the customary 0.3; linear interpolation at the cut) and divided by fpr_max → aupro in [0, 1]. Returns aupro, fpr / pro (the curve up to the cut), n_regions, fpr_max.

Raises ValueError on empty / mismatched / non-finite input, non-binary masks, no defect region, no good pixel, or fpr_max outside (0, 1].
