Individual action recognition is to recognize independently the actions of athletes surrounded by a blue box in the upper figure. In this research, I will recognize the action of the entire scene based on the action of all players in the scene (group activity recognition). Please look at the player surrounded by a red box in the upper figure. Maybe, you can only understand that this player is jumping. However, as a whole scene, it is important that the player on the left side performs spiking and the player on the right side performs blocking. In team sports like this, group action including the context of the entire scenes is important.
