This paper introduces an Adaptive Temporal Window Selection (ATWS) framework to address security challenges in person re-identification for broadcast and internet video, focusing on dynamic attack detection. The ATWS framework dynamically adjusts temporal window sizes based on real-time motion dynamics, attack likelihood scores, and detection confidence metrics, aiming to optimize detection performance in dynamic environments.
Key findings
The ATWS framework dynamically adjusts temporal windows for attack detection in PRBI systems.
Includes a Temporal Dynamics Analyzer, Adaptive Window Controller, and Multi-Scale Attack Detector.
Proposes a reinforcement learning-based approach for optimal window size selection.
Offers a principled method to balance detection latency and accuracy in surveillance environments.
Limitations & open questions
The framework's performance in real-world scenarios with diverse attack types is yet to be validated.
The computational overhead introduced by the adaptive mechanism needs further optimization.
