Model evaluation metrics for image object detection problems.
Evaluates prediction quality of labeled bounding boxes.
Output only. The total number of bounding
boxes (i.e. summed over all images) the ground
truth used to create this evaluation had.
Output only. The bounding boxes match metrics
for each Intersection-over-union threshold
0.05,0.10,...,0.95,0.96,0.97,0.98,0.99 and each
label confidence threshold
Output only. The single metric for bounding boxes
evaluation: the mean_average_precision averaged over all
