MIT researchers are developing some interesting technology that could supercharge our cell phone cameras. Dubbed “Eulerian Video Magnification”, the project’s goal is to amplify “hidden” information by revealing the subtle changes in standard video too difficult for the naked eye to detect. For example, you can input a video of a person simply staring at the camera, process it with the video magnification technology, and it’ll output a video that shows the person’s face pulsating red to visualize the actual flow of blood in and out of the face. The technology is powerful enough to even detect the pulsations of the radial artery in a video of one’s wrist. It’s amazing stuff, and it brings a lot of potential for contact-free medical sensors and monitoring devices.
Take a look at the video below explaining the technology and demonstrating some examples. There’s a lot of technical jargon, so you may want to skip ahead to the 1:25 mark to see the really cool stuff.
