Object Detection
Not just 'what' is in the image, but 'where'.
What you will learn
- ✓Classification vs detection
- ✓Bounding boxes
- ✓Why real-time detection matters
Explanation
Image classification says what an image contains. Object detection goes further: it locates each object with a bounding box and a label.
Models like YOLO ('You Only Look Once') do this fast enough for video, drawing boxes around people, cars, and more in real time.
This powers self-driving perception, security cameras, and retail analytics.
Real-world use
A self-driving car uses object detection to box and track every nearby pedestrian and vehicle, frame by frame.
Common mistakes
- • Confusing classification (one label per image) with detection (boxes for many objects).

List three products that rely on real-time object detection and why.
