Anomalyze: Hybrid GNN and Transformer for Crowd Anomalies

  • Unique Paper ID: 178790
  • PageNo: 5164-5171
  • Abstract:
  • This research proposes a hybrid model integrating GNN and Transformer architectures to detect crowd anomalies in real-time. The GNN component models the interactions between individuals in the crowd, while the Transformer captures long-range dependencies across video sequences. The hybrid approach enables robust identification of abnormal crowd behaviors, such as sudden dispersal, panic, or the presence of obstacles. Evaluation on benchmark datasets such as UCSD and UMN demonstrates improved accuracy, efficiency, and generalization compared to traditional methods like CNN-LSTM and handcrafted feature-based models. This work provides a foundation for real-time surveillance systems that ensure public safety in crowded environments
