How is the hidden background generated when an object/person is cropped out of a photo?

177 views

For example, you have a photo of two people in the foreground and a library in the background. Someone uses software or an app to remove one (or even both) of them from the photo.

What I don’t understand is how they fill in the part of the background that was originally hidden from view by the person standing in front of it. Can someone please explain this to me?

Another interesting fact:

You have a spot in your eyes, where you are physically unable to see. There are tests online, where you only look at an image with one eye, and after staring long enough, a point disappears.

But your brain still fills in that information with the surrounding information. It can’t see the point anymore, and a bit around it. But it just generates a believable background.

Computers/AI/Photoshop can do the same thing as your brain.
