Using Photographs To Enhance Videos 102
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.

Really, the ability for their software to 'unwrap' a 3D object and allow you to fiddle with it as you wish is very cool.
And not limited to a 'static' scene.
And, really, if you're going to go to the effort of videoing a scene, then photographing the scene, then passing the video and the photos through their software. All to get better exposure and resolution.
Um.
Wouldn't it be a far better cost/effort equation to just buy a better HD camera in the damn first place?

All of these techniques are pretty awesome and will certainly be a boon to home video enthusiasts the world over (plus plenty of commercial places that are on a tight budget), but I've got another idea.
You see it on TV all the time, CCTV footage of robberies and the like, couldn't this technology be used to effectively map out a 3D image of the purpetrator?
I know it wont be perfect and most CCTV is probably too low quality to be used, but it would certainly be pretty cool (and useful) to have a vaugely accurate 3D model of the guy, giving you height, build, etc. and with the help of supplementary images, a really easy way to adjust it's appearance.

I would say that mounting a high res still camera in parallel with the CCTV camera and taking, say 1 picture every 10 seconds after the CCTV montion sensors are tripped, which would have quality comparable to a high-end consumer camera (i.e. 7-8 Mpixels), then use that data to enhance the video taken to aid in identifying suspects
That said, I don't think these 'enhanced' videos should be admissible as evidence, since the videos have been effectively tampered with and given the possibility of altering identifying features of a suspect using superimposition of a different picture on the video could either cause the wrong person to be jailed, or the actual criminal set free
