ELFNet

This is a PyTorch implementation of the paper ELFNet: Evidential Local-global Fusion for Stereo Matching (ICCV 2023).

Environment

You can create a conda environment with following commands.

conda create env -n elfnet python=3.8
conda activate elfnet
conda install pytorch torchvision torchaudio pytorch-cuda=11.7 -c pytorch -c nvidia
pip install -r requirements.txt
