How Does a Computer Actually See?

Imagine you're looking at a picture of a dog, and someone asks you to describe it. You might say 'It has four legs, a tail, and fur.' A computer does something similar when it sees an image, it breaks the picture into tiny pieces, like pixels, and looks for patterns in them. These patterns help the computer understand what it's seeing, like whether it’s a dog or a cat.
