How LoGeR Extends 3D Reconstruction to Thousands of Frames with Hybrid Memory

LoGeR, a new long‑context geometric reconstruction framework from DeepMind and UC Berkeley, uses a hybrid memory module combining test‑time‑training (TTT) and sliding‑window attention (SWA) to enable feed‑forward 3D reconstruction over sequences of up to tens of thousands of frames, achieving state‑of‑the‑art accuracy on KITTI, VBR, 7‑Scenes, ScanNetV2 and TUM‑Dynamics benchmarks.
