What is Object Detection
Detecting and localizing objects in images
Object Detection is a computer vision task that involves detecting instances of objects of certain classes in images or video along with their locations.
Main Approaches
- Two-stage detectors — R-CNN, Fast R-CNN, Faster R-CNN
- Single-stage detectors — YOLO, SSD, RetinaNet
- Transformers — DETR, DINO
Popular Models
- YOLOv8/v9 — fast real-time detection
- Faster R-CNN — high accuracy
- EfficientDet — balance of speed and accuracy
- RT-DETR — transformer for real-time
Quality Metrics
- mAP (mean Average Precision) — main metric
- IoU (Intersection over Union) — box overlap
- FPS — frames per second processing speed
Business Applications
- Quality control in manufacturing
- Video analytics and security
- Object counting and inventory
- Autonomous vehicles
