Since the world is usually considered a three-dimensional environment, it would seem natural for image processing to attempt to recover and utilize as much information about the three-dimensional aspects of an image as possible. That has not been the case, mainly because the process of recovering three-dimensional information in a reliable and simple manner has been elusive.
