5.6.2.1. The mAP and COCO AP Metrics

Average precision and average recall are averaged over multiple Intersection over Union (IoU) values.

Two metrics are used for accuracy evaluation in the dla_benchmark application. The mean average precision (mAP) is the challenge metric for PASCAL VOC. The mAP value is averaged over all 80 categories using a single IoU threshold of 0.5. The COCO AP is the primary challenge for object detection in the Common Objects in Context contest. The COCO AP value uses 10 IoU thresholds of .50:.05:.95. Averaging over multiple IoUs rewards detectors with better localization.
