ReLift: Dense 3D Tracking via Geometric Trajectory Repair
October 30, 2026
ReLift is a feed-forward framework that treats dense 3D tracking from monocular video as a geometric trajectory repair and completion task. It leverages pretrained 2D trackers and 3D geometry models to interpolate occluded segments and correct depth/correspondence errors.
HOW THIS AFFECTS YOU
●
builderYou can implement more robust 3D tracking in monocular video applications.
●
researcherThis demonstrates that lifting 2D trajectories can rival dedicated 3D trackers when combined with repair loops.
