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

191 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?

The original photo will have contextual clues (sky, trees, architecture, etc) but the real “trick” is the photo manipulating AI has seen many MILLIONS of photos and learned “rules” about what kind of things belong where in an image.

It can’t make something unexpected (if your friend was standing in front of a sign it can’t know what was on the sign) but trees, buildings, continuing an object that’s in other parts of the image, easy peezy
