Computer Imaging Technology Creates X-Ray Videos: Rotoscoping

Imagine being able to see inside an animal and watch its bones move. Imagine if scientists had a better way to study moving skeletons and doctors had a better way to diagnose and study skeletal injuries. This capability may no longer be out of reach. Stephen Gatesy and David Baier, NSF-funded researchers at Brown University, have developed a method of clearly observing the movement of skeletons of living animals.
Using a novel technique called scientific rotoscoping, the researchers simultaneously record standard video of moving animals and X-ray images of their moving skeletons. From these images an animated 3-D computer model of the moving skeleton overlaid on the digital recording of the moving animal can be used to study coordinated skeletal movement with animal movement for the first time.
