GeoLatent: Geometry-Guided Latent Structuring with Routed Optimization for 3D Reasoning

Despite progress in vision-language models, 3D spatial reasoning from 2D images remains challenging. Text-based methods describe intermediate geometry with discrete tokens, limiting fidelity for continuous spatial relations. Continuous latents offer richer representations, but a single latent type does not explicitly s...

Physically Plausible Video Generation via Visual-Semantic Chain-of-Events Conditioning

This paper reformulate PPVG as event-centric generation by representing physical evolution as a chain of causally connected and physically constrained events, and generates videos with superior physical plausibility across diverse domains.

VisualRouter: Query-Grounded Visual Sampling for Long Video Understanding

This paper proposes VisualRouter, a training-free and plug-and-play framework for query-grounded visual sampling, which consistently improves multiple LVLMs over uniform sampling, and outperforming existing training-free visual sampling methods under the same setting.
