Teaching AI to see.
What is Computer Vision?
Making computers understand images and videos.
Like teaching a computer to "see" like humans!
How Computers See Images
Images are made of pixels (tiny dots).
Each pixel has a color value (0-255 for each: Red, Green, Blue).
AI reads these numbers!
Common Tasks
**Image Classification**: What's in the image? - Cat or dog? - Apple or orange?
**Object Detection**: Where is it in the image? - Find all cars in photo - Locate faces
**Image Segmentation**: Outline exact shape - Separate person from background - Medical image analysis
Real-World Uses
**Face Unlock**: iPhone Face ID **Self-driving Cars**: Detect pedestrians, signs **Medical**: Detect diseases in X-rays **Retail**: Checkout without cashier **Social Media**: Auto-tag friends in photos
Example in Action
Instagram filters: 1. Detect your face 2. Find eyes, nose, mouth 3. Add filter effects
Simple Concept
AI learns by seeing thousands of examples: - Show 10,000 cat pictures - AI learns cat features - AI can identify new cat pictures
