Using Photographs To Enhance Videos
seussman71 writes with a link to some very interesting research out of the University of Washington that employs "a method of using high quality photographs to enhance a video taken of the same subject. The project page gives a good overview of what they are doing and the video on the page gives some really nice examples of how their technology works. Hopefully someone can take the technology and run with it, but one thing's for sure: this could make amateur video-making look even better than it does now." And if adding mustaches would improve your opinion of the people in amateur videos, check out the unwrap-mosaics technique from Microsoft Research.
Takeo Kanade's lab at Carnegie Mellon's Robotics Institute did this in the mid 90's...

like the way they "stereoscopically" create a depth-map from a _single_ still photograph
TFV said they were using video frames to do stereoscopic depth-mapping. Since the source footage changed perspective, they can build a depth map based on the relative shift of each object in the video, and then project the high-quality photograph on top of the derived 3D structure
