The data in this table comes from the ZEB: Zero-shot Evaluation Benchmark for Image Matching proposed in the paper. This benchmark consists of 12 public datasets that cover a variety of scenes, weather conditions, and camera models, corresponding to the 12 test sequences starting from GL3 in the table. We will release ZEB as soon as possible.

  • Inference code
    • gim_roma
    • gim_dkm
    • gim_loftr
    • gim_lightglue
  • Training code

We are actively continuing with the remaining open-source work and appreciate everyone's attention.

πŸ€— Online demo

Go to Huggingface to quickly try our model online.

βš™οΈ Environment

I set up the running environment on a new machine using the commands listed below.

conda install pytorch==1.10.1 torchvision==0.11.2 torchaudio==0.10.1 cudatoolkit=11.3 -c pytorch -c conda-forge
pip install albumentations==1.0.1 --no-binary=imgaug,albumentations
pip install pytorch-lightning==1.5.10
pip install opencv-python==4.5.3.56
pip install imagesize==1.2.0
pip install kornia==0.6.10
pip install einops==0.3.0
pip install loguru==0.5.3
pip install joblib==1.0.1
pip install yacs==0.1.8
pip install h5py==3.1.0

πŸ”¨ Usage

Clone the repository

git clone https://github.com/xuelunshen/gim.git
cd gim

Download gim_dkm model weight from Google Drive

Put it on the folder weights

Run the following command

python demo.py --model gim_dkm

or

python demo.py --model gim_lightglue

The code will match a1.png and a2.png in the folder assets/demo
, and output a1_a2_match.png and a1_a2_warp.png.

Click to show a1.png and a2.png.

Click to show a1_a2_match.png.

a1_a2_match.png is a visualization of the match between the two images

Click to show a1_a2_warp.png.

a1_a2_warp.png shows the effect of projecting image a2 onto image a1 using homography

There are more images in the assets/demo folder, you can try them out.

Click to show other images.
