anomaly_pixel_f1_max — SPC anomaly_eval op

• 数据种类:video × video → table

• 调用: import fullseye as fs; fs.ledger.anomaly_pixel_f1_max(scores, masks)(要直接调用实现,import anomeval; anomeval.anomaly_pixel_f1_max(scores, masks);从台账取用则 opsspc.get("anomaly_pixel_f1_max"))

用法

由异常得分图与缺陷掩膜,求遍历所有阈值的像素级 F1 最大值(table)。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

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.
