| Abstract(in English) | This paper proposes a player and ball tracking method in tennis videos with image processing techniques. The proposed method detects four corners of the tennis court using Hough-transform, and players and a ball using YOLOv4, which is one of Convolutional Neural Networks(CNNs). The bound position and hitting point are detected by using the changes in the velocity vectors of the ball. Then, these coordinates are converted with a perspective transformation and displayed to users. In the experiment, the detection accuracies of the players and the ball have reached 0.99 and 0.84 in terms of the recall ratio, respectively. For the bound position and the hitting point, the recall ratio and the distance error on the tennis court were 0.60 and about 1.2 [m], respectively. |
