LoGeR: Long-Context Geometric Reconstruction with Hybrid Memory

This repository contains the reimplemented model checkpoints for LoGeR, as presented in the paper LoGeR: Long-Context Geometric Reconstruction with Hybrid Memory.

LoGeR processes long video streams in chunks with a hybrid memory design to improve large-scale geometric reconstruction quality and consistency.

Checkpoints

We provide two main pre-trained models. To use them, please clone the corresponding GitHub repository and place the downloaded .pt files in your local ckpts/ directory as follows:

• ckpts/LoGeR/latest.pt
• ckpts/LoGeR_star/latest.pt

Download Commands

You can download the weights directly via wget:

# Download LoGeR
wget -O ckpts/LoGeR/latest.pt https://huggingface.co/Junyi42/LoGeR/resolve/main/LoGeR/latest.pt?download=true

# Download LoGeR_star
wget -O ckpts/LoGeR_star/latest.pt https://huggingface.co/Junyi42/LoGeR_star/latest.pt?download=true

Usage

For detailed instructions on installation, running demos, and evaluation, please refer to the main GitHub repository.
