Half Hidden
In object recognition an AI finds things in a picture. It also says where exactly they are.
What you'll learn in this level
- Why some things are easier to spot than others
- What occlusion means for an AI
- Why an AI sees differently than you do
What the AI Finds in a Picture
In object recognition an AI finds things in a picture. It also says where exactly they are.
This sits in self-driving cars. Also in cameras that watch over places. And in phone apps that add things to the picture.
How Object Recognition Works
- 1
Find features
The AI looks for certain patterns, shapes, colours and surfaces. That is how it tells things apart.
- 2
Neural networks
A neural network is a computer model that learns. It practises on millions of labelled pictures. After that it knows thousands of kinds of things.
- 3
Confidence numbers
For every find the AI says how sure it is. That number is called a confidence value.

The hard part
It gets hard when things are half hidden. Or when they lie in a strange way. Or when the light is bad.
Here you find out how an AI spots things in very different scenes.
Guess first, then experiment
A cup stands half behind a book. You spot it at once. And the AI?
