• 2024.4.30: Release checkpoint weights of surface normal and dichotomous image segmentation.
• 2024.4.7: Add HuggingFace App demo.
• 2024.4.6: Release inference code and depth checkpoint weight of GenPercept in the GitHub repo.
• 2024.3.15: Release arXiv v2 paper, with supplementary material.
• 2024.3.10: Release arXiv v1 paper.

conda create -n genpercept python=3.10
conda activate genpercept
pip install -r requirements.txt
pip install -e .

Download the pre-trained models genpercept_ckpt_v1.zip from BaiduNetDisk (Extract code: g2cm), HuggingFace, or Rec Cloud Disk (To be uploaded). Please unzip the package and put the checkpoints under ./weights/v1/.

Then, place images in the ./input/$TASK_TYPE dictionary, and run the following script. The output depth will be saved in ./output/$TASK_TYPE. The $TASK_TYPE can be chosen from depth, normal, and dis.

sh scripts/inference_depth.sh

For surface normal estimation and dichotomous image segmentation , run the following script:

bash scripts/inference_normal.sh
bash scripts/inference_dis.sh

Thanks to our one-step perception paradigm, the inference process runs much faster. (Around 0.4s for each image on an A800 GPU card.)
