WorldForge V2: Eliciting Camera-Trajectory Alignment in Video Diffusion Models

Video diffusion models have learned rich 3D/4D priors, making them promising for scene generation and video re-rendering. However, their use in spatial tasks is limited by imprecise camera control, spatial and temporal inconsistencies, and entangled camera motion with scene dynamics. Existing approaches, such as task-s...

World in World: Explore the World with World Models

World in World is presented, a training-free inference-time interface that converts heterogeneous control evidence into camera- and time-labelled clean visual states, which are read through the native self attention of a frozen causal video model.

GS$^{2}$CI: Robust Gaussian Splatting For Snapshot Compressive Imaging via Large Vision Model Priors

This work proposes a novel framework that reconstructs high-quality 3D scenes from a single SCI measurement by leveraging 3D Gaussian Splatting and the powerful priors of large-scale vision foundation models (VFMs) and introduces Opacity-Guided Splitting and Growth Regulation (OSGR), an SCI-specific densification strat...
