In the analysis of video footage of ball sports, it is necessary for the analyst to watch all of the game footage and record the necessary information. In this study, we propose a method for automatically extracting scenes in which scores are displayed from the broadcast ball game video, focusing on the score displays common across various ball sports broadcasts. In the proposed method, the score board area is estimated by frame difference. Then, scenes in which scores are displayed are extracted by analyzing the difference between the average image of the estimated area and individual frames. Furthermore, the score area is estimated by frame difference and background subtraction to predict the time of score changes. The experimental results showed zero overextractions and an unextraction rate of 4% of the total for scene extraction, while for score change time estimation, there were 2 overestimations and 1 unestimation. |
