- nl 14y agomicro-expressions .. were very short in duration rather than in magnitude. So this would be the wrong kind of amplification This is exactly the kind of amplification you need. Something like the movement caused by mirror of an SLR camera (at the end of their demo) is very very short in duration, but they amplify the magnitude AND slow the video to allow it to be visible.
- taliesinb 14y agoNo, my point is that micro-expressions don't need to be amplified, because they are perfectly large in magnitude, just very short. So all you need is a freeze-frame.
- tsumnia 14y agoSome amplification is still needed in my opinion, but you are correct. Amplifying the video of a high speed camera should aid in the some of the expression detection. Instead of something like eye movement, think something more subtle, like a person's brow being furrowed.
