T-WLA: Bridging Slow Vision and Fast Touch

Kaichen Zhou, Yuzhen Chen, Hannah Yao +14

In contact-rich manipulation, contact conditions can change before a visual policy updates its action plan. Recomputing the plan through the visual policy adds latency, while tacti…

Representation-guided in-context learning for medical image interpretation with multimodal large language models

Minda Zhao, Fangyu Hu, Yan Luo +8

Medical image interpretation is central to diagnosis and care, yet adapting general-purpose multimodal large language models (MLLMs) often requires resource-intensive domain-specif…

MemoBench: Benchmarking World Modeling in Dynamically Changing Environments

Haoyu Chen, Kaichen Zhou, Hang Hua +11

Video generation models aspire to simulate dynamic environments, and several benchmarks now evaluate memory consistency across frames. However, most assess consistency only while t…

PaintCopilot: Modeling Painting as Autonomous Artistic Continuation

Yunge Wen, Yaluo Wang, Yuancheng Shen +2

Existing neural painting methods are target-driven: given a reference image, strokes are optimized to reconstruct it, fixing the outcome before painting begins. We instead ask whet…

GEM-4D: Geometry-Enhanced Video World Models for Robot Manipulation

Kaichen Zhou, Yuzhen Chen, Fangneng Zhan +8

Video world models can generate realistic futures from a single instruction, but they often fail to track the same physical points consistently across time. As a result, the genera…

Stream3D: Sequential Multi-View 3D Generation via Evidential Memory

Kaichen Zhou, Zeyang Bai, Xinhai Chang +3

View-conditioned 3D generators such as SAM 3D, TRELLIS, and Hunyuan3D produce high-quality object reconstructions from a single view, but real-world visual observation often arrive…

DENALI: A Dataset Enabling Non-Line-of-Sight Spatial Reasoning with Low-Cost LiDARs

Nikhil Behari, Diego Rivero, Luke Apostolides +3

Consumer LiDARs in mobile devices and robots typically output a single depth value per pixel. Yet internally, they record full time-resolved histograms containing direct and multi-…

Abstract 3D Perception for Spatial Intelligence in Vision-Language Models

Yifan Liu, Fangneng Zhan, Kaichen Zhou +3

Vision-language models (VLMs) struggle with 3D-related tasks such as spatial cognition and physical understanding, which are crucial for real-world applications like robotics and e…

PAGE-4D: Disentangled pose and geometry estimation for vggt-4d perception

Kaichen Zhou, Yuhan Wang, Grace Chen +5

Recent 3D feed-forward models, such as the Visual Geometry Grounded Transformer (VGGT), have shown strong capability in inferring 3D attributes of static scenes. However, since the…

Visual Acoustic Fields

Yuelei Li, Hyunjin Kim, Fangneng Zhan +7

Objects produce different sounds when hit, and humans can intuitively infer how an object might sound based on its appearance and material properties. Inspired by this intuition, w…
