New SAMV-DUSt3R model disentangles 3D scenes using SAM2 masks

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced SAMV-DUSt3R, a novel end-to-end model designed to disentangle objects from 3D scenes by integrating SAM2 2D masks into the MV-DUSt3R reconstruction process. This method utilizes a Cross Flow Mask Block to guide the network towards specific instances, thereby enhancing shape accuracy and achieving object-level separation without requiring multi-stage pipelines. A Spatial RankGNN component further stabilizes reconstruction by selecting optimal reference views with 73.5% accuracy. Experiments show SAMV-DUSt3R improves average reconstruction precision by 11% over existing methods, offering benefits for applications in driving, robotics, AR/VR, and digital heritage. AI

IMPACT This method could advance applications in robotics, AR/VR, and digital heritage by improving 3D scene understanding and object manipulation.

    SAMV-DUSt3R: Instance-Centric 3D Scene Decoupling from Sparse Multi-Views

    arXiv:2609.11279v1 Announce Type: new Abstract: With the rising demand to decouple objects from 3D scenes, we propose SAMV-DUSt3R, an end-to-end model that injects SAM2 2D masks into MV-DUSt3R reconstruction. A Cross Flow Mask Block uses these masks to steer the network toward th…
