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.
