With just a single image, SIFU is capable of reconstructing a high-quality 3D clothed human model, making it well-suited for practical applications such as 3D printing and scene creation. At the heart of SIFU is a novel Side-view Conditioned Implicit Function, which is key to enhancing feature extraction and geometric precision. Furthermore, SIFU introduces a 3D Consistent Texture Refinement process, greatly improving texture quality and facilitating texture editing with the help of text-to-image diffusion models. Notably proficient in dealing with complex poses and loose clothing, SIFU stands out as an ideal solution for real-world applications.</em> </div>:open_book: For more visual results, go checkout our <a href="https://river-zhang.github.io/SIFU-projectpage/" target="_blank">project page</a>

If you don't have conda or miniconda, please install that first:
sudo apt-get update && \
sudo apt-get upgrade -y && \
sudo apt-get install unzip libeigen3-dev ffmpeg build-essential nvidia-cuda-toolkit
mkdir -p ~/miniconda3 && \
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O ~/miniconda3/miniconda.sh && \
bash ~/miniconda3/miniconda.sh -b -u -p ~/miniconda3 && \
rm -rf ~/miniconda3/miniconda.sh && \
~/miniconda3/bin/conda init bash && \
~/miniconda3/bin/conda init zsh
# close and reopen the shell
git clone https://github.com/River-Zhang/SIFU.git
sudo apt-get install libeigen3-dev ffmpeg
cd SIFU
conda env create -f environment.yaml
conda activate sifu
pip install -r requirements.txt
Please download the checkpoint (google drive) and place them in ./data/ckpt
Please follow ICON to download the extra data, such as HPS and SMPL (using fetch_hps.sh
and fetch_data.sh
). There may be missing files about SMPL, and you can download from here and put them in /data/smpl_related/smpl_data/.
Inference
python -m apps.infer -cfg ./configs/sifu.yaml -gpu 0 -in_dir ./examples -out_dir ./results -loop_smpl 100 -loop_cloth 200 -hps_type pixie
Testing
# 1. Register at http://icon.is.tue.mpg.de/ or https://cape.is.tue.mpg.de/
# 2. Download CAPE testset
bash fetch_cape.sh
# evaluation
python -m apps.train -cfg ./configs/train/sifu.yaml -test
# TIP: the default "mcube_res" is 256 in apps/train.
Texture Refinement Module
The code is available for download on google drive. Please note that the current code structure may not be well-organized and may require some time to set up the environment. The author plans to reorganize it at their earliest convenience.
