How computers understand pictures!
Imagine a jigsaw puzzle. When you see a finished puzzle, you can tell what's in the picture!
Computer vision works like that!
Computers break images into tiny pieces (pixels) and figure out what's in them - just like solving a puzzle!
Images on a computer are just numbers!
📊 Each pixel has a number representing its color
🖤 A black pixel might be number 0
⚪ A white pixel might be number 255
The computer looks at all these numbers and finds patterns!
🚗 Self-driving cars: See roads, other cars, pedestrians
📱 Face unlock: Recognize your face to unlock your phone
🏥 Medical scans: Find diseases in X-rays and MRIs
📸 Photo filters: Add funny ears to your selfie!
🤖 Robots: Help robots navigate the world
We show computers millions of pictures that are already labeled!
"This is a cat" - 100,000 times!
"This is a dog" - 100,000 times!
Eventually, the computer learns to tell them apart by itself!
Computer vision isn't perfect:
❌ Can be confused by weird angles
❌ Hard to see in poor lighting
❌ Might confuse similar objects (bus vs truck)
But it's getting better every day!
