FOCUS: Fine-Grained Open-Vocabulary Change Detection for Uncertainty-Aware Semi-Static Scenes

Can Xu, Mingfeng Yuan, Mahan Mohammadi +1

Autonomous robots operating over long periods must keep their environmental memory up to date as the world changes between visits. In semi-static environments, an object may be rep…

BeyondSight: Object Permanence for End-to-End Autonomous Driving

Sandro Papais, Letian Wang, Mudit Jain +2

Autonomous driving operates in partially observable environments where actors may become fully occluded by other vehicles or infrastructure. Most end-to-end driving systems implici…

Video Generation Models are General-Purpose Vision Learners

Letian Wang, Chuhan Zhang, Rishabh Kabra +9

Driven by next-token prediction, NLP shifted from task-specific models into powerful generalist foundation models. What, then, is the equivalent catalyst needed to achieve a genera…

JDT3D: Addressing the Gaps in LiDAR-Based Tracking-by-Attention

Brian Cheong, Jiachen Zhou, Steven Waslander

Tracking-by-detection (TBD) methods achieve state-of-the-art performance on 3D tracking benchmarks for autonomous driving. On the other hand, tracking-by-attention (TBA) methods ha…
