E-TraMamba: A New Paradigm for Efficient Long-Term 3D Feature Tracking with Event Cameras

Juwei Shen, Yujie Wu, Changwen Chen

Event-based 3D tracking enables low-latency and high-speed perception, while existing CNN- and Transformer-based trackers struggle to capture long-range spatiotemporal dependencies in sparse, noisy event streams, especially under real-time and efficiency constraints. To address t…

Hierarchical 3D Scene Graph Construction and Belief-based Planning for Semantic Navigation

Bing Wu, Zuyao Chen, Changwen Chen

Semantic navigation is a fundamental task for embodied agents operating in unseen environments, requiring both semantic understanding and long-term decision-making. Recent foundation models have empowered agents with rich semantic priors for this task. However, without structured…
