What is computer vision?

Artificial IntelligenceLesson on requestFree to read

Quick answer

Computer vision is the field of AI that lets computers interpret and understand images and video — recognizing objects, faces, text, and scenes the way humans do with their eyes. It turns pixels into meaning: detecting, classifying, and locating things in images.

Key things to understand

  1. It turns pixels into meaning: detecting, classifying, and locating things in images.
  2. Modern computer vision is powered by neural networks trained on labeled images.
  3. Uses: face unlock, self-driving cars, medical scans, quality inspection.
  4. It can be fooled and reflects biases in its training data.

People also ask

How does computer vision work?
Neural networks learn patterns from millions of labeled images, then detect those patterns in new images.
Where is computer vision used?
Face recognition, self-driving cars, medical imaging, retail checkout, and manufacturing inspection.
Is computer vision always accurate?
No — it can be fooled by unusual inputs and can inherit biases from its training data.
