Mixture-of-Thought-Tokens: Unifying Perception and Reasoning for Free-form Multimodal Grounding
Tianyi Gao, Han Fang, Tianyi Ding +9
Multimodal Large Language Models have made great progress in grounding tasks, yet existing methods still struggle to unify precise localization and complex reasoning. For one thing…
GeoAnchor: Collaborative Reasoning via Latent Decomposition for 3D Spatial Understanding
Hao Li, Han Fang, Zixin Pan +8
GeoAnchor introduces a framework that breaks down 3D spatial information from 2D images into position, direction, and geometry latent components, enabling more accurate and interpr…
DrivingDepth: Sparse-Prompted Pixel-wise Scale Correction for Driving Depth Estimation
Chi Huang, Wenhao Zhang, Hang Yin +5
Dense depth estimation for autonomous driving faces a geometry-scale conflict: depth foundation models deliver pixel-aligned dense visual geometry without reliable metric scale, wh…
Monte Carlo Energy Aggregation for Mobile 3D Gaussian Splatting
Xiaobiao Du, YuAn Wang, Hao Li +3
Recent advances in 3D Gaussian Splatting have demonstrated unprecedented success in novel view synthesis. However, the substantial inference and storage overhead driven by high-ord…
Any4D: Open-Prompt 4D Generation from Natural Language and Images
Hao Li, Qiao Sun
While video-generation-based embodied world models have gained increasing attention, their reliance on large-scale embodied interaction data remains a key bottleneck. The scarcity,…
Unified Reward Model for Multimodal Understanding and Generation
Yibin Wang, Yuhang Zang, Hao Li +2
Recent advances in human preference alignment have significantly improved multimodal generation and understanding. A key approach is to train reward models that provide supervision…
