Toward Comprehensive 3D Grounding: Orientation Grounding through Vision-Language Models

Tuo Liang, Disheng Liu, Nengbo Wang +2

Grounding is a core capability of spatial vision-language models, yet most existing work focuses only on where a referred object is. Many 3D tasks also require knowing how it is or…

Filling the Unseen: Scene Extrapolation via 3D Gaussian Splatting

Yunlai Zhou, Yiren Lu, Tuo Liang +3

3D Gaussian Splatting achieves photorealistic reconstruction within training view distribution, yet it degrades on out-of-distribution novel views, exhibiting holes in unobserved r…

Computational Humor with Multimodal LLMs: Methods, Datasets, Evaluation, and Challenges

Tuo Liang, Zhe Hu, Disheng Liu +2

Multimodal humor in memes, cartoons, and comics remains difficult for AI systems because intended meaning depends on non-literal mechanisms, shared cultural knowledge, and communic…
