MIT has developed an unusual video enhancement technology.

In many Hollywood (and not only Hollywood) films there are scenes when a policeman asks his hacker friend to improve the quality of the video, which depicts the main villain. In a couple of seconds, a hacker usually copes with the most incredible tasks, “pulling” very clear frames from the face of our villain from a completely unwatchable video, while the frames are cleared of noise, detailed and increased several times.

It is clear that such technologies exist (not so perfect, really), but in Hollywood they usually demonstrate absolutely fantastic work of such hackers. But now, perhaps, Hollywood screenwriters can sleep peacefully - the developers at the Massachusetts Institute of Technology (MIT) have created a technology that allows you to see the invisible.

A poor-quality video can be improved to such an extent that it will be possible to distinguish the pulse of a person on the hand of a person caught in the frame. In this video is not shot in FullHD quality. On the video below, you will immediately understand what is being said - it’s quite difficult to explain the technology created by MIT engineers, it’s better to see with your own eyes.

According to the developers, the filter used in the technology is called “Eulerian Video Magnification”. In each case, this filter allows you to track the color change of literally every pixel in the "picture". After analyzing and processing the data, it becomes possible to improve the video, and the improvement is very significant (in some cases, the video quality, so to speak, is superior to the original - the smallest details appear and increase).

On the video shown below, you can track all these improvements. If you get tired of watching, scroll through the video at 3:18.
