GNAVI: Golf navigation system based on player information

In sports videos, text provides valuable information about the game such as scores and information about the players. This paper provides a golf navigation system based on this player information. In the case of baseball and soccer, the location of key captions such as scoreboard captions is generally fixed during the game. However, in golf, the location of the key captions containing player information is not fixed. These captions cannot be determined from fixed locations. Therefore, we use a color pattern of captions and its repetition property instead of the location property to determine these key captions. We also propose a dual binarization method easily segmenting texts with different color polarities (i.e. dark and bright texts) from the background in the key captions. From this text information, we provide each segment with player information and create the golf navigation system. By conducting experiments on a large database, the system performance is demonstrated to be accurate and robust.
