Whether it’s for computer games, motion analysis in sports, or even medical examinations, many applications require that people and their movements are captured digitally in 3D in real-time. Until now, this was possible only with expensive systems of several cameras, or by having people wear special suits. Computer scientists have now developed a system that requires only a single video camera. It can even estimate the 3D pose of a person acting in a pre-recorded video, for instance a YouTube video.
