Abstract
Abstract. The paper considers the problem of identifying game events in a video game of beach volleyball. As a method for solving the problem, a combined approach is proposed based on recognizing the trajectory of the ball and constructing skeletal representations of the players. Temporal localization of game events is carried out by searching for the changes in the ball trajectory using the construction of a composite Bezier curve. Spatial localization is performed by the positioning of the ball and the players in the frame at the moment of the trajectory change. The classification is based on the skeletal representation of the player touching the ball. The experiments performed show that the algorithm is able to perform spatiotemporal localization with high precision and recall.
