sigmoid(X)<1, IF：box_confidence<prob_threshold THEN: confidence=box_confidence*sigmoid(class_score)<box_confidence<prob_threshold, So there is no need to calculate class_score when box_confidence<prob_threshold，and the confidence of most anchors is lower than the prob_threshold.

sigmoid(X)<1,
IF：box_confidence<prob_threshold
THEN: confidence=box_confidence*sigmoid(class_score)<box_confidence<prob_threshold,
So there is no need to calculate class_score when box_confidence<prob_threshold，and the confidence of most anchors were lower than the prob_threshold.
