Creating 3-D-printed “motion sculptures” from 2-D videos

New England Patriots quarterback Tom Brady has often credited his success to spending countless hours studying his opponent’s movements on film. This understanding of movement is necessary for all living species, whether it’s figuring out the best angle for throwing a ball, or perceiving the motion of predators and prey. But simple videos can’t actually give us the full picture. That’s because traditional videos and photos for studying motion are two-dimensional, and don’t show us the underlying 3-D structure of the person or subject of interest. Without the full geometry, we can’t inspect the small and subtle movements that help us move faster or make sense of the precision needed to perfect our athletic form. Recently, though, researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have come up with a way to get a better handle on this understanding of complex motion.  The new system uses an algorithm Continue reading Creating 3-D-printed “motion sculptures” from 2-D videos
