HANDGUN DETECTOR (YOLOV4)

Brief Introduction

This model detects handguns.

I created this model back in 2021, so it's not a cutting-edge solution. Also, because it's an older model, it's large in size and not suitable for running a demo in a browser, so there isn't a demo available for it. 

Number of classes

1 class: (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 %

IoU threshold = 50 %, used Area-Under-Curve for each unique Recall

mean average precision (mAP@0.50) = 0.939233, or 93.92 %
