Function compute_ap

Compute Average Precision at a set IoU threshold (default 0.5). Returns: mAP: Mean Average Precision precisions: List of precisions at different class score thresholds. recalls: List of recall values at different class score thresholds. overlaps: [pred_boxes, gt_boxes] IoU overl

(gt_boxes, gt_class_ids,
               pred_boxes, pred_class_ids, pred_scores,
               iou_threshold=0.5)
