HumanTracker: Towards Comprehensive and Human-Aligned Motion Tracking Benchmark

Dairu Liu, Zekun Qi, Jiayu Zeng +11

Humanoid motion tracking is central to teleoperation and whole-body imitation, yet evaluation often disagrees with what people perceive in videos. Kinematic errors average per-fram…

DA-Nav: Direction-Aware City-Scale Vision-Language Navigation

Ye Yuan, Kehan Chen, Xinqiang Yu +7

The paper presents DA-Nav, a direction-aware vision‑language navigation system that uses commercial map directions and reformulates navigation as discrete spatial grounding on an e…

LIMMT: Less is More for Motion Tracking

Yu Guan, Zekun Qi, Chenghuai Lin +7

We argue that high-quality motion data can steer tracking policies toward better optimization trajectories early in training. In this work, we introduce LIMMT (Less Is More for Mot…

Humanoid-GPT: Scaling Data and Structure for Zero-Shot Motion Tracking

Zekun Qi, Xuchuan Chen, Dairu Liu +10

We introduce Humanoid-GPT, a GPT-style Transformer with causal attention trained on a billion-scale motion corpus for whole-body control. Unlike prior shallow MLP trackers constrai…

OmniSpatial: Towards Comprehensive Spatial Reasoning Benchmark for Vision Language Models

Mengdi Jia, Zekun Qi, Shaochen Zhang +5

Spatial reasoning is a key aspect of cognitive psychology and remains a bottleneck for current vision-language models (VLMs). While extensive research has aimed to evaluate or impr…

Hybrid-grained Feature Aggregation with Coarse-to-fine Language Guidance for Self-supervised Monocular Depth Estimation

Wenyao Zhang, Hongsi Liu, Bohan Li +7

Current self-supervised monocular depth estimation (MDE) approaches encounter performance limitations due to insufficient semantic-spatial knowledge extraction. To address this cha…
