PointVG-R: Internalizing Geometric Reasoning in MLLMs for Precise Pointing Localization via Visual Chain of Thought
Ling Li, Bowen Liu, Zinuo Zhan +5
Pointing-based visual grounding requires models to precisely locate target objects by deciphering complex spatial relationships between the visual scene and pointing gestures. Trad…
VistaRef: Boosting Visual Spatial Orientation Awareness for Pointing-to-Object Detection
Ling Li, Zhizhen Cai, Xinkun Wu +4
Grounding deictic gestures in natural images is fundamental to AR and human-robot collaboration, providing a basis for seamless spatial interaction. While Transformer-based visual…
From Sparse to Dense: Spatio-Temporal Fusion for Multi-View 3D Human Pose Estimation with DenseWarper
Ling Li, Changjie Chen, Yuyan Wang +4
In multi-view 3D human pose estimation, models typically rely on images captured simultaneously from different camera views to predict a pose at a specific moment. While providing…
Beyond Language: Grounding Referring Expressions with Hand Pointing in Egocentric Vision
Ling Li, Bowen Liu, Zinuo Zhan +4
Traditional Visual Grounding (VG) predominantly relies on textual descriptions to localize objects, a paradigm that inherently struggles with linguistic ambiguity and often ignores…
