Image registration

Image registration is like a game of matching pictures. Imagine you have two pictures of the same thing, but one is a little bit different than the other, like a puzzle with a few missing pieces. Your job is to make the pictures match perfectly, even with the missing piece.

To do this, you have to use special tools, kind of like special eyes and hands, to move the pictures around and make them fit properly. You might have to stretch one picture or shrink it a little bit, or rotate it to match the other picture's direction.

Once the two pictures match perfectly, you can superimpose them on top of each other, like putting one transparency on top of another transparency. This is called image registration. It helps us see things more clearly by combining different views of the same thing, like looking through two different cameras at the same time.

Image registration is used to create things like 3D models of objects, maps of the earth, and even medical images of a person's body. It's like magic, but it's actually science!
