Beyond a Single Crop: Contextualized Embeddings for Player Re-Identification

Here, we propose ContextReID, a contextualized embedding framework that represents a player by jointly considering other players in the same frame and observations from different frames of the broadcast sequence.

Key points

  • Person re-identification is typically addressed by learning identity-discriminative embeddings from individual person crops.
  • However, player re-identification in broadcast sports videos presents a unique challenge: players from the same team often share similar appearances, while video sequences provide repeated observations of the same players under different viewpoints and surrounding contexts.
  • A combined contextual learning and retrieval objective encourages the model to capture cross-frame identity relationships while maintaining discriminative embeddings for player matching.
  • These results highlight the utility of spatial and temporal context for reliable player identification in broadcast sports videos.
