This has obvious motorsport applications if one begins thinking about it. And the beauty is one can apply it retroactively to video that's already "in the can" so to speak so that anyone can perform this motion analysis on any video they capture. Link to code ( http://people.csail....du/mrub/vidmag/ ) and a web based interface ( http://videoscope.qrclab.com/ ) included in piece.

Maybe it could make tire modes visible to the hoi polloi. Or find the front suspension travel in an F1 car.

Blimey. One of these days there won't be room for intuition, guess-work and the 'black arts'.

Every engine lab will get this setup.

And every law enforcement agency.

Every laboratory!

This is so obvious (in hindsight) it is incredible it hasn't been done before.

I think that's VERY true in this case. I would even consider this clever idea worthy of a patent, unlike most software.

... it is incredible it hasn't been done before.


Well, this does require digital video and the computing power to process it, so it couldn't have been done, say, 30 years ago.

And damn I wish I had thought of it.

After some reflection, it occur to me that the colour and contrast amplification is not that tricky - just an extension of what has been done for years in terms of adjusting thresholds and gains. Motion amplification is more complex - requiring recognition of features in each frame, tracking the movement then amplifying that movement.

I have circulated the link at my work and a lot of people are keen to put it to use. A fantastic tool.
