This one is pretty amazing: a team of MIT researchers have created a technique to amplify small changes in a video clip that enables us to see minute changes that otherwise would've been unnoticeable (see 3:20 where they made a person's arterial pulse visible). They called it Eulerian Video Magnification:
"Our goal is to reveal temporal variations in videos that are difficult or impossible to see with the naked eye and display them in an indicative manner. Our method, which we call Eulerian Video Magnification, takes a standard video sequence as input, and applies spatial decomposition, followed by temporal filtering to the frames. The resulting signal is then amplified to reveal hidden information. Using our method, we are able to visualize the flow of blood as it fills the face and also to amplify and reveal small motions. Our technique can run in real time to show phenomena occurring at temporal frequencies selected by the user."

PlayhousePalsAmazing ... especially the baby's heartbeat view =oO
StormsingerShades of "Zoom and Enhance"!
Real life is finally catching up to Hollywood.
bmacs27says...Bill Freeman is a really cool guy. I had a chance to have lunch with him, and we were talking about all the work he's doing. He's the kind of guy that just explores things because he thinks they're cool. Like this one project he had where he wanted to take a picture of earth from space using entirely earth based equipment using the reflection off of the moon. Absolutely ridiculous.
kceaton1Just as above my first though was of space use, but for a much more practical application.
So when a body in a solar system is moving around it's host star (they can deduce how many planets there are in that area) also moves by a function of gravity. Usually this is painstaking work that must be done, but if this little procedure is accurate enough they could start to apply it to the search for new planets and their discover and it should make the process, especially for the SMALLER planets, MUCH faster. I hope someone watches this with their breakfast in the morning as I bet EVERY researcher would want this tool.
Awesome software interpolation!

You ruined my joke, but that's the first thing I thought too.

spawnflaggerHopefully this technique won't be used in the future to ruin another Bourne movie...
hpqpI foresee casinos and government agencies being keenly interested in this tech.
dannym3141This is one of the most futuristic cool as hell looking things i've seen in my life. I can think of so many uses for this. Absolutely amazed by it.
