Computer vision is a field of AI that enables computers to interpret and understand visual information from the world — images, videos, and live camera feeds. It’s how your phone unlocks with your face, how self-driving cars detect pedestrians, and how Instagram automatically identifies objects in photos.
What Computer Vision Can Do
- Image classification — identifying what’s in an image (cat, car, building)
- Object detection — locating and identifying multiple objects within an image
- Facial recognition — identifying or verifying a person by their face
- Image segmentation — precisely outlining every object in an image
- Optical Character Recognition (OCR) — reading text from images
- Visual search — finding similar images or products from a photo
Real-World Applications
- Face unlock on smartphones
- Google Lens identifying objects from photos
- Medical imaging — AI diagnosing from X-rays or MRIs
- E-commerce visual search (find products that look like this photo)
- Security cameras with motion and people detection
- Quality control in manufacturing
Computer Vision for Website Owners
- Auto-generate alt text for images (accessibility + SEO)
- Moderate user-uploaded images for inappropriate content
- Enable visual product search in WooCommerce stores
- Analyze heatmaps of where visitors look on your pages
