Trajectory Prediction in Dynamic Object Tracking: A Critical Study

2025-06-24

AI Summary

This work addresses critical challenges in dynamic object tracking (DOT) and trajectory prediction (TP)—namely, poor generalizability, high computational overhead, strong data dependency, and salient ethical risks. We propose a novel TP framework integrating multimodal perception, semantic understanding, and contextual modeling. Methodologically, it unifies lightweight feature extraction, semantic-segmentation-guided state estimation, and context-aware graph neural network learning, while embedding privacy-preserving mechanisms and explainability constraints. Empirical evaluation across autonomous driving, security surveillance, and industrial robotics demonstrates that our approach reduces annotation dependency by 30%, improves cross-domain generalization accuracy by 12.7%, cuts inference latency by 45%, and enables GDPR-compliant anonymized trajectory generation. The study systematically elucidates a synergistic optimization pathway balancing robustness, efficiency, and ethics in TP, offering a scalable methodological foundation for deploying high-assurance intelligent systems.
