ELI5: Explain Like I'm 5

Visual information fidelity

Imagine you have a picture of your favorite animal. Now imagine that you want to send this picture to a friend who lives far away. You can't just give them the real animal, so you take a picture of it instead.

When you take a picture of the animal, you want to make sure that it looks as much like the real animal as possible. You want the colors to be the same, the details to be clear, and the picture to be easy to understand.

This is what we call "visual information fidelity." It means making sure that the picture you take looks as much like the real thing as possible, so that people can easily recognize what it is.

There are lots of things that can affect visual information fidelity. For example, if you take a picture in a dark room, the colors might not look right. If you take a blurry picture, it might be hard to see the details. And if you take a picture from the wrong angle, it might be hard to tell what the animal is.

So, when we talk about visual information fidelity, we're really talking about how well a picture represents the real thing. The better the fidelity, the closer the picture looks to the real thing.
