MV-DUSt3R+: Single-Stage Scene Reconstruction from Sparse Views In 2 Seconds

no code implementations9 Dec 2024 Zhenggang Tang, Yuchen Fan, Dilin Wang, Hongyu Xu, Rakesh Ranjan, Alexander Schwing, Zhicheng Yan

To make our method robust to reference view selection, we further propose MV-DUSt3R+, which employs cross-reference-view blocks to fuse information across different reference view choices.
