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

185 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?

Like others have said, it’s using AI to fill the hole. You can’t guarantee that you’ll get exactly what’s behind the object (obviously), but ideally it’s a very convincing creation based on very informed guesses based on how the AI was trained

Btw, the formal term for this is image inpainting, if you want a more in-depth info. You mentioned in another reply that you were curious who invented it. There’s a (technical) paper or two talking about the history of (digital) inpainting.
