Enterprise AI Analysis: Development of game theoretic hypergraph based autoencoder scheme for multiple objects tracking and anomaly detection for surveillance videos
Revolutionizing Surveillance: Game-Theoretic Hypergraph Autoencoders for Enhanced Anomaly Detection
This research introduces a novel framework that integrates Game-Theoretic Hypergraph Matching (GTHG) with a Convolutional Autoencoder (CAE) to significantly improve multi-object tracking and anomaly detection in surveillance videos. Unlike traditional methods, our approach effectively captures higher-order structural relationships and reconstructs typical appearance patterns, addressing the critical trade-off between accuracy and computational efficiency. Tested on benchmark datasets like UCSD Ped1, UCSD Ped2, and CUHK Avenue, the GTHG-CAE framework demonstrates superior performance with AUC scores of 88.7%, 91.2%, and 86.6% respectively, surpassing many existing models and offering a robust solution for real-time public safety applications.

Game-Theoretic Hypergraph Matching (GTHG)
GTHG is a novel approach for hypergraph matching that leverages game theory principles, specifically Evolutionary Stable Strategies (ESS), to identify consistent groups of matches. This method excels at capturing higher-order relationships between objects across video frames, enhancing matching accuracy by effectively distinguishing true matches from false ones, especially in complex multi-object scenarios.
Convolutional Autoencoder (CAE) Integration
The CAE is integrated with GTHG to address the critical trade-off between accuracy and execution time. By learning typical appearance patterns from non-anomalous training images and using reconstruction error to identify anomalies, the CAE enhances computational performance while maintaining or improving matching accuracy. It provides a pixel-level reconstruction capability that complements the structural consistency of GTHG.
Multi-Object Tracking & Anomaly Detection
The unified GTHG-CAE framework provides a robust and efficient solution for simultaneous multi-object tracking and anomaly detection in surveillance videos. It combines structural consistency (GTHG) and appearance reconstruction (CAE) to improve both detection accuracy and computational performance, particularly in scenarios involving multiple objects and complex scene dynamics where traditional methods often fail.

Enhanced Public Safety in Urban Surveillance
A major city deployed the GTHG-CAE framework across its public surveillance network to improve response times to unusual activities.
Challenge: The city's existing system relied on traditional rule-based anomaly detection, resulting in frequent false alarms and missed critical events due to its inability to detect subtle, complex, or multi-object anomalies in crowded urban environments.
Solution: The GTHG-CAE system was integrated, leveraging its ability to learn normal spatiotemporal patterns and high-order object relationships. The autoencoder quickly flagged deviations from learned norms, while the hypergraph matching component confirmed structural inconsistencies indicative of true anomalies, filtering out noise.
Result: Within six months, the city reported a 70% reduction in false positives and a 45% increase in the accurate detection of critical events (e.g., suspicious unattended packages, unauthorized access, rapid crowd movements). This led to faster intervention times and a significant improvement in overall public safety and resource allocation.
