Achieving state-of-the-art performance in both 4D reconstruction and point tracking, Uni4R leverages continuous velocity fields to model dynamics at any timestamp, breaking free from traditional limitations.
High-curvature regions in point clouds can be effectively represented by a novel hyperbolic rectification method that boosts discriminative power and captures fine geometric details.
Training on the Human4K dataset yields substantial gains in 3D human reconstruction accuracy, especially in depth-ambiguous scenarios.
