One Scene, Two Depths: Probing Geometric Ambiguity in Monocular Foundation Models

Xiaohao Xu, Feng Xue, Xiang Li +5

A faithful 3D world representation should account for layered geometry, where a single camera ray may contain multiple visible and geometrically valid surfaces. Monocular depth est…

Latent Geometry Beyond Search: Amortizing Planning in World Models

Hoang Nguyen, Xiaohao Xu, Xiaonan Huang

Modern vision-based world models can represent observations as compact yet expressive latent manifolds, but fast goal-oriented planning in these spaces remains challenging. This ra…

Probing Collision Grounding in Vision-Language Models for Safe Human-Robot Collaboration

Jun Wang, Xiaohao Xu, Xiaonan Huang

Safe human--robot collaboration requires more than visual description: a monitor must determine whether the robot body is safely separated, already colliding with the scene or a pe…

When Search Becomes Memory: Accelerating Robot Design Discovery with Self-Evolving Skills

Yunfei Wang, Xiaohao Xu, Yang Li +1

Large language models (LLMs) are increasingly used as proposal generators for evolutionary robot design, yet most loops remain memoryless: simulator results shape the next populati…

The 3D Mirage: Probing and Taming 3D Hallucinations

Hoang Nguyen, Xiaohao Xu, Xiaonan Huang

Monocular depth foundation models achieve remarkable generalization by learning large-scale semantic priors, but this creates a critical vulnerability: they hallucinate illusory 3D…

Whole-Body Proprioceptive Morphing: A Modular Soft Gripper for Robust Cross-Scale Grasping

Dong Heon Han, Xiaohao Xu, Yuxi Chen +5

Biological systems, such as the octopus, exhibit masterful cross-scale manipulation by adaptively reconfiguring their entire form, a capability that remains elusive in robotics. Co…

Visual Anomaly Detection under Complex View-Illumination Interplay: A Large-Scale Benchmark

Yunkang Cao, Yuqi Cheng, Xiaohao Xu +6

The practical deployment of Visual Anomaly Detection (VAD) systems is hindered by their sensitivity to real-world imaging variations, particularly the complex interplay between vie…

ViSA-Flow: Accelerating Robot Skill Learning via Large-Scale Video Semantic Action Flow

Changhe Chen, Quantao Yang, Xiaohao Xu +2

One of the central challenges preventing robots from acquiring complex manipulation skills is the prohibitive cost of collecting large-scale robot demonstrations. In contrast, huma…

Towards Ambiguity-Free Spatial Foundation Model: Rethinking and Decoupling Depth Ambiguity

Xiaohao Xu, Feng Xue, Xiang Li +5

Depth ambiguity is a fundamental challenge in spatial scene understanding, especially in transparent scenes where single-depth estimates fail to capture full 3D structure. Existing…

Scalable Benchmarking and Robust Learning for Noise-Free Ego-Motion and 3D Reconstruction from Noisy Video

Xiaohao Xu, Tianyi Zhang, Shibo Zhao +8

We aim to redefine robust ego-motion estimation and photorealistic 3D reconstruction by addressing a critical limitation: the reliance on noise-free data in existing models. While…

Hierarchical Multi-Graphs Learning for Robust Group Re-Identification

Ruiqi Liu, Xingyu Liu, Xiaohao Xu +3

Group Re-identification (G-ReID) faces greater complexity than individual Re-identification (ReID) due to challenges like mutual occlusion, dynamic member interactions, and evolvin…
