VideoReloc: Long-Term Indoor Video Relocalization against a Kilobyte-Scale Semantic Scene Graph

This work introduces VideoReloc, whose adaptive clips use odometry to gather spatial evidence until object and motion criteria are met, adapting query length to the observed scene, and reframes sparse-map relocalization as verification of spatially extended video queries.

CinemaTraj: Composing Atomic Camera Trajectories for 3D Scenes with LLM Agents

CinemTraj is presented, a framework that reframes camera trajectory planning as a language-grounded spatial reasoning problem that produces prompt-faithful, collision-free trajectories with high cinematographic quality, outperforming existing approaches on prompt alignment, trajectory quality, and safety metrics.
