A visualization system called "Multi-motion" has been developed. It shows a gymnast's form and locus in the vault. It extracts player's image area quickly and automatically, and displays image of their form sequentially from the jump to the finish, overlaying the images on a scene like a stroboscopic camera, even in the case where the background has a complex pattern including moving objects such as walking spectators. To achieve this, a new extraction method has been developed. This method uses motion analysis based on the facts that "A player is bigger and moving faster, and spectators in the background are smaller and moving slower." The system was used in the live broadcast of the World Gymnastics Championship and it gained favor in the public and gymnastic community.
