Computer Vision
📋 What it is
Computer vision is AI that “sees” — it finds patterns of pixels to recognise objects, faces, or text in images.
🗣️ Coach says
To a computer, an image is just a grid of numbers (pixel colours). Computer vision finds PATTERNS in those numbers — edges, shapes, textures — to recognise a face or a stop sign. It doesn’t “see” a cat; it matches a pattern.

Why was the chatbot such a good listener?
It was trained on a lot of input!
😲 Whoa!
Self-driving cars use computer vision to spot pedestrians and signs — but they can be fooled by a few stickers on a stop sign, because they match patterns, not meaning.
✅ Quick check: How does a computer “see” a photo?
Say your answer out loud first — then reveal.
As a grid of numbers (pixel colours); vision AI finds patterns in those numbers to recognise objects.
Images are numeric to a computer; vision is pattern-matching over pixels.
🧪 Try it! (2 minutes)
Zoom way into a digital photo until you see the squares (pixels). That grid of colours is what AI “sees”.
