New 3D Morphological Perturbations boost video model depth accuracy

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new optimization-free regularizer called 3D Morphological Perturbations to improve 3D scene representations like NeRF and 3D Gaussian Splatting (3DGS). This method treats each Gaussian in 3DGS as a fundamental unit and applies perturbations to its scale, rotation, and pruning parameters. The approach eliminates the need for costly per-scene 3DGS optimization during dataset curation and enables models to learn stronger geometric priors. When integrated into a 14B-parameter video model via ControlNet, it reduced mean depth error by 12.5% and improved robotics policy success rates by up to 8.0% on manipulation tasks. AI

IMPACT Enhances geometric priors in 3D video models, potentially improving robotics and simulation accuracy.

    Rethinking 3D Noise: Learning 3D-Aware Video Priors via Optimization-Free Morphological Perturbations

    arXiv:2609.03657v1 Announce Type: new Abstract: 3D scene representations like NeRF and 3D Gaussian Splatting (3DGS) suffer severe artifacts in sparse-view settings. Recent generative 3D artifact fixers attempt to address this, but rely on paired corrupted and clean renders requir…
