SHERF learns a Generalizable Human NeRF to animate 3D humans from a single image.

Figure 1. SHERF is a single image-based generalizable Human NeRF. With just one inference pass on a single image, SHERF reconstructs Human NeRF in the canonical space which can be driven and rendered for novel view and pose synthesis.

This repository will contain the official implementation of SHERF: Generalizable Human NeRF from a Single Image.

📣 Updates

[08/2023] Training and inference codes for RenderPeople, THuman, HuMMan and ZJU-Mocap are released.

🖥️ Requirements

NVIDIA GPUs are required for this project. We recommend using anaconda to manage the python environments.

    conda create --name sherf python=3.8
    conda install pytorch==1.11.0 torchvision==0.12.0 torchaudio==0.11.0 cudatoolkit=11.3 -c pytorch
    conda install -c fvcore -c iopath -c conda-forge fvcore iopath
    conda install pytorch3d -c pytorch3d (or pip install --no-index --no-cache-dir pytorch3d -f https://dl.fbaipublicfiles.com/pytorch3d/packaging/wheels/py38_cu113_pyt1110/download.html)
    pip install -r requirements.txt
    conda activate sherf

Set up Dataset

RenderPeople Dataset

Please download our rendered multi-view images of RenderPeople dataset from OneDrive.

THuman Dataset

Please follow instructions of MPS-NeRF to download the THuman dataset. After that, please download our estimated SMPL Neutral parameters.

HuMMan Dataset

Please follow instructions of HuMMan-Recon to download the HuMMan dataset.

ZJU-Mocap dataset

Please follow instructions of Neural Body to download the ZJU-Mocap dataset.

Tips: If you hope to learn how to render multi-view images, You may refer to XRFeitoria, a rendering toolbox for generating synthetic data photorealistic with ground-truth annotations.

🏃‍♀️ Inference

Download Models

The pretrained models and SMPL model are needed for inference.

The pretrained models are put in OneDrive and Baidu Pan (pin:gu1q) for downloading.

Register and download SMPL models here. Put the downloaded models in the folder smpl_models. Only the neutral one is needed. The folder structure should look like

./
├── ...
└── assets/
    ├── SMPL_NEUTRAL.pkl
