Visualization System for Player's Sequential Forms at Sports Broadcasting

抄録

We developed a visualization system for sports broadcasting that informs TV viewers of a sports player's sequential performing forms and locus in detail when gymnastic game such as 'vault' is broadcasted. It records the corresponding frames while a player is performing, extracts only the player's performing forms from background scenes by a proposed algorithm, superposes them sequentially on a background scene, and broadcasts them with slow speed. This system named as 'Multi-Motion' has ever been used in NHK live broadcasting for 1995 World Gymnastics Championships held in Japan.
