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.
Why Hacker News points people here: Cited as the canonical demonstration of pulling out invisible signals like pulse from video, with commenters imagining other applications.
“they amplified color changes. So the tiny flushes caused by the heartbeat were clearly visible”HN comment, 2015
“detecting a persons pulse rate from video”
Detecting pulse from video
Between Paul Ekman's work in behavioral science and detecting a persons pulse rate from video ( this video ), it seems like one could have a pretty decent "lie detector" running on a smart phone.
“video to MIT paper submitted to SIGGRAPH about emphasizing video features, blood flow among them”
MIT paper video amplifying features like blood flow
"read your heartrate" reminded me of this video (video to MIT paper submitted to SIGGRAPH about emphasizing video features, blood flow among them)
“they amplified color changes. So the tiny flushes caused by the heartbeat were clearly visible”
Amplified color changes make heartbeat flushes visible
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 this video (from 1m30s)
“Reminds me of those visualizations designed for magnifying tiny changes”
Magnifies tiny changes, possible climate application
Reminds me of those visualizations designed for magnifying tiny changes, Eulerian Video Magnification: this video Perhaps a potential application?
“A similar technique to reduce the amplitude of strobing seems plausible.”
Technique could reduce strobing amplitude
>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: this video A similar technique to reduce the amplitude of strobing seems plausible.
