• 呼叫: import fullseye as fs; fs.ledger.anomaly_pixel_f1_max(scores, masks)(要直接呼叫實作,import anomeval; anomeval.anomaly_pixel_f1_max(scores, masks);從台帳取用則 opsspc.get("anomaly_pixel_f1_max"))
由異常得分圖與缺陷遮罩,求遍歷所有閾值的像素級 F1 最大值(table)。
> 以下的詳細說明為原文 —— 摘要與標題已翻譯。
scores and masks are (n, H, W) (or lists / single 2-D maps); a pixel is predicted defective when its score is >= the threshold. The F1 = 2TP / (2TP + FP + FN) is evaluated exactly at every distinct score (sorted cumulative sums, no threshold grid); the highest threshold wins a tie. Returns f1, threshold, precision and recall at the maximum, n_pos and n_neg (pixels). It counts pixels, like the pixel AUROC, not regions (see anomaly_pro): a small defect weighs little however well it is found.
Raises ValueError on empty / mismatched / non-finite input, non-binary masks, or when the masks contain no defect pixel or no good pixel.
