Light of Normals: Unified Feature Representation for Universal Photometric Stereo

ICLR 2026poster

Universal photometric stereo (PS) is defined by two factors: it must (i) operate under arbitrary, unknown lighting conditions and (ii) avoid reliance on specific illumination models. Despite progress (e.g., SDM UniPS), two challenges remain. First, current encoders cannot guarantee that illumination…

Adjacent-view Transformers for Supervised Surround-view Depth Estimation

IROS 2025

Depth estimation has been widely studied and serves as the fundamental step of 3D perception for robotics and autonomous driving. Though significant progress has been made in monocular depth estimation in the past decades, these attempts are mainly conducted on the KITTI benchmark with only front-vi

SURDS: Benchmarking Spatial Understanding and Reasoning in Driving Scenarios with Vision Language Models

NeurIPS 2025poster

Accurate spatial reasoning in outdoor environments—covering geometry, object pose, and inter-object relationships—is fundamental to downstream tasks such as mapping, motion forecasting, and high-level planning in autonomous driving. We introduce SURDS, a large-scale benchmark designed to systematica…

WMNav: Integrating Vision-Language Models into World Models for Object Goal Navigation

IROS 2025

Object Goal Navigation-requiring an agent to locate a specific object in an unseen environment-remains a core challenge in embodied AI. Although recent progress in Vision-Language Model (VLM)-based agents has demonstrated promising perception and decision-making abilities through prompting, none has

DyGait: Exploiting Dynamic Representations for High-performance Gait Recognition

ICCV 2023poster

Gait recognition is a biometric technology that recognizes the identity of humans through their walking patterns. Compared with other biometric technologies, gait recognition is more difficult to disguise and can be applied to the condition of long-distance without the cooperation of subjects. Thus,…
