The video accompanying the SIGGRAPH 2012 paper on Eulerian Video Magnification. It amplifies subtle changes in ordinary video, such as skin color shifts from a heartbeat, to reveal pulse and tiny motions.

Cited as the canonical demonstration of pulling out invisible signals like pulse from video, with commenters imagining other applications.

Between Paul Ekman's work in behavioral science and detecting a persons pulse rate from video ( [VIDEO] ), it seems like one could have a pretty decent "lie detector" running on a smart phone.

"read your heartrate" reminded me of [VIDEO] (video to MIT paper submitted to SIGGRAPH about emphasizing video features, blood flow among them)

I remember a similar technique (maybe it's from the same people) where they amplified color changes. So the tiny flushes caused by the heartbeat were clearly visible [VIDEO] (from 1m30s)

Reminds me of those visualizations designed for magnifying tiny changes, Eulerian Video Magnification: [VIDEO] Perhaps a potential application?

>What can we hack together that can be used to filter seizures? I think a video filter could do this. See this video on Eulerian Video Amplification from SIGGRAPH 2012: [VIDEO] A similar technique to reduce the amplitude of strobing seems plausible.
