Speed3R: Sparse Feed-forward 3D Reconstruction Models

arXiv CS.CV

ArXi:2603.08055v1 Announce Type: new While recent feed-forward 3D reconstruction models accelerate 3D reconstruction by jointly inferring dense geometry and camera poses in a single pass, their reliance on dense attention imposes a quadratic complexity, creating a prohibitive computational bottleneck that severely limits inference speed. To resolve this, we
