Researchers at MIT have developed a crazy process called Eulerian Video Magnification that seems like it was pulled straight from a science fiction movie. It reveals the "subtle changes in the world" that are otherwise imperceptible to the human eye, like an artery pumping in a wrist. Spoiler: kinda gross!
So how does it work? It picks up on the very slight nuances in a video that you can't detect, such as the way a face reddens as blood is pumped through the body. It grabs these visualizations from a video sequence, and applies spatial decomposition then temporal filtering to the frames. Then it amplifies the color so these nuances become amazingly dynamic and easy to see. More here.
This is so cool, thanks for sharing this, wow.
