Development of motion analysis system for quantitative evaluation of teamwork in soccer games

We present a motion analysis system of soccer games. The purpose of this system is to evaluate the teamwork quantitatively based on the movement of all the players in a game. Space management and cooperative movement by the players are two major factors for teamwork evaluation. To quantify them from motion images, we propose two new features; "minimum moving time pattern" and "dominant region". From experiments using actual game scenes, it is suggested that the proposed system can be a new tool for supporting to evaluate the teamwork.
