This model detects handguns.

 

Number of classes: 1 (handgun)

 

Metrics:

detections_count = 1485, unique_truth_count = 659
class_id = 0, name = Handgun, ap = 93.92%        (TP = 590, FP = 72)
for conf_thresh = 0.25, precision = 0.89, recall = 0.90, F1-score = 0.89
for conf_thresh = 0.25, TP = 590, FP = 72, FN = 69, average IoU = 77.47 %
