Traditional surveillance systems often focus on direct interactions in less populated settings. In contrast, IRE-Net is designed to operate effectively in complex, real-world environments where multiple individuals are present. Dr. Ruize Han, the project’s corresponding researcher, states, “IRE-Net is built to overcome the shortcomings of current surveillance technologies by analyzing the dynamics of crowded scenes.”
The system uses a combination of appearance and spatial information to analyze interactions. Its core technology involves a structure known as the pairwise-interactive-relation cube, along with a multi-head, multi-task module that predicts the type and context of human interactions.
Preliminary testing indicates that IRE-Net performs better than existing technologies in recognizing non-contact interactions in crowded settings, with improvements noted in reducing false positives and negatives.
IRE-Net also has potential applications in urban planning and crowd management. This technology can provide valuable insights aiding the design and management of public spaces.
Future enhancements for IRE-Net include integrating multi-camera systems to broaden its applicability across diverse environments. “We are planning to expand the system’s capabilities to include a network of cameras, enhancing our analysis of large public areas,” Dr. Han explains.
