(Video link) MIT scientists have developed a computer algorithm that exaggerates subtle movements and color changes in videos. First developed to monitor sleeping newborns, the technology reveals changes that are otherwise invisible to the naked eye. It turns out, for example, that people's faces flush red with each heartbeat.
When applied to other small movements in the world around us, such as the wobbling of a construction crane or the micro-movements in an eye, the enhanced motion has a startling impact, a lot like seeing time lapse for the first time.
