TrackEverything: Long Horizon Dense Tracking via De-Duplicating 3D Scene Representationsarxiv.org

TrackEverything is a novel 3D point tracker that overcomes the trade-off between sparse long-horizon tracking and dense short-clip tracking. It represents videos as persistent 3D scene tracks, scaling with unique physical geometry rather than video duration, and achieves dense tracking for over 1000 frames within 40 GB of GPU memory.
