Eulerian Video Magnification for Revealing Subtle Changes in the World.

Hi Everybody. I found this very interresting video analysis/enhancment tool made by MIT.
It compares pixels in a video to enhance colour or movement, and shows subtle movement /colour variations normally not captured by the eye.
Im currently not using the programme myself as im to daft to figure out how to make the fromt end work,
and im no good at command line inputs :blink:
But im not unable to see the potentiale for this software.
People are already wondering if its possible to use this as a kind of lie detector, or maybe find out something new about plants and other seemingly static objects.
Im hoping sombody will pick up on this, and maybe make a small tutorial for the common man.
The programme only runs on 64 bit maschines and uses the EVM mathlab compiler to run the data, so you will need 2 downloads to make this work, but im sure those interrested will figure it out.

Have fun.

Despite the lack of comments on this, I think the article is fascinating.

Thanks for sharing, I only just found the time to read it (too much work, not enough play these days, I'm in danger of becoming very dull).  :D

This opens up amazing possibilities for digital photography!
 eg using video clips from digital cameras to:
monitor patients in hospital (or at home?)
assess the stability/safety of cranes and other engineering structures eg road bridges to provide warnings before the structures fail.
There are bound to be many, many, other remote sensing possibilities which could save lives and enable medical and scientific knowledge and progress to be made.
I agree this is fascinating.
What do you think?

Amazing work by a very clever research team. Thank you Kim.diedrichsen.7 for sharing the info here.

No need to be put off by command line input or lack a 64-bit machine, there's an easy online interface where you can try it out.

http://videoscope.qrclab.com/

There you can experiment with different processing options using several video clips they provide, and you can upload your own clip and experiment with that. Fascinating stuff!
