That explains it.
Actually, it might. Some students at Carnegie Mellon University are showing off a system whereby
3-dimensional data can be interpolated from a single 2D image, based on recognizing key features like the ground, the sky, people, and so on. The
is strikingly impressive, taking a variety of photos and then turning them into virtual pop-up books.
Then again, the technology is still limited. I’m certain a computer
hypothesize information not shown in the photo. I’m also fairly certain they have a good chance of getting it wrong.
