Three Domains in AI
Artificial Intelligence, or AI, is a way to make computers and machines smart so they can do
tasks that usually need human intelligence. AI can work in different ways depending on the kind
of information it uses. We can group AI into three important areas: Computer Vision, Natural
Language Processing, and Using Data to find Patterns.
Computer Vision
Computer Vision helps computers “see” and “understand” what is in pictures or videos, almost
like how our eyes and brain work together. Since computers don’t have eyes like humans, they
use cameras to take pictures. Then, special programs help them recognise objects, people, or
places in those pictures.

For example, think about self-driving cars. They have cameras all around that help them see
the road, other cars, traffic lights, and pedestrians so they can drive safely without a human
driver.
Some applications of computer vision are as follows:
• Face unlock on phones: Uses your face to unlock the device safely.
• Self-driving cars: Detects roads, traffic signs, and obstacles to drive automatically.
