| Abstract(in English) | We can track multiple players from basketball game videos using image recognition and Multi Object Tracking technologies. However, occlusions among basketball players and framing out/in of them make the tracking task difficult. In this paper, we track players using uniform number constraints that only players with limited uniform numbers appear in a game unless any player is substituted. Because 10 players play basketball, 10 different uniform numbers appear in a game. By assigning a set of uniform number candidates to each player, we infer the unidentified uniform numbers from the uniform numbers that have been identified. In an evaluation experiment, we performed tracking tasks using 3 basketball game videos in which various occlusions occur, and compared two methods with and without uniform number constraints using the recall, precision, and f-value measures. |
