Abstract: Techniques related to game focus estimation in team sports for multi-camera immersive video are discussed. Such techniques include selecting regions of a scene comprising a sporting event, generating a node graph and sets of features for the selected regions, and determining a game focus region of the selected regions by applying a graph node classification model based on the node graph and sets of features.
