Most of you will have played the jigsaw puzzle games. You get a lot of small pieces of a images, where you need to assemble them correctly to form a big real image. **The question is, how you do it?** What about the projecting the same theory to a computer program so that computer can play jigsaw puzzles? If the computer can play jigsaw puzzles, why can't we give a lot of real-life images of a good natural scenery to computer and tell it to stitch all those images to a big single image? If the computer can stitch several natural images to one, what about giving a lot of pictures of a building or any structure and tell computer to create a 3D model out of it?
Well, the questions and imaginations continue. But it all depends on the most basic question? How do you play jigsaw puzzles? How do you arrange lots of scrambled image pieces into a big single image? How can you stitch a lot of natural images to a single image?

The answer is, we are looking for specific patterns or specific features which are unique, which can be easily tracked, which can be easily compared. If we go for a definition of such a feature, we may find it difficult to express it in words, but we know what are they. If some one asks you to point out one good feature which can be compared across several images, you can point out one. That is why, even small children can simply play these games. We search for these features in an image, we find them, we find the same features in other images, we align them. That's it. (In jigsaw puzzle, we look more into continuity of different images). All these abilities are present in us inherently.
