| Abstract(in English) | In professional baseball, metadata such as ball speed and the count are generated with every pitch. That data is delivered by data broadcasting and the Internet. Experts must create the data manually because automatic pitch identification is difficult. We are therefore developing a system that can identify the type of pitch automatically based on features obtained from professional baseball video. The system measures trajectory shape and change of speed. It also measures the motion of a catcher by using SIFT features. It obtains pitch speed by character recognition from broadcast video. The system classifies pitches with high accuracy using these features. |
