MERG3R: A Divide-and-Conquer Approach to Large-Scale Neural Visual Geometry
MERG3R is a training-free, model-agnostic divide-and-conquer framework that enables neural visual geometry models to scale to large, unordered image collections by partitioning data into manageable subsets and merging local reconstructions into a globally consistent 3D model, thereby overcoming GPU memory limitations while improving accuracy and scalability.
