# DeVRF: Fast Deformable Voxel Radiance Fields for Dynamic Scenes
[Project page](https://jia-wei-liu.github.io/DeVRF) | [arXiv](https://arxiv.org/abs/2205.15723)
> **TL;DR:** A novel representation and learning paradigm for dynamic radiance fields reconstruction -- 100x faster, no loss in dynamic novel view synthesis quality.
## 📢 News
- [2022.10.10] We release the first-version of DeVRF code and dataset!
- [2022.9.15] DeVRF got accepted by [**NeurIPS 2022**](https://nips.cc/)!
- [2022.6.1] We release the arXiv paper.
## 📝 Preparation
### Installation
```
git clone https://github.com/showlab/DeVRF.git
cd DeVRF
pip install -r requirements.txt
```
[Pytorch](https://pytorch.org/) and [torch_scatter](https://github.com/rusty1s/pytorch_scatter) installation is machine dependent, please install the correct version for your machine.
Dependencies (click to expand)
- `PyTorch`, `numpy`, `torch_scatter`, `pytorch3d`: main computation.
- `scipy`, `lpips`: SSIM and LPIPS evaluation.
- `tqdm`: progress bar.
- `mmcv`: config system.
- `opencv-python`: image processing.
- `imageio`, `imageio-ffmpeg`: images and videos I/O.
- `Ninja`: to build the newly implemented torch extention just-in-time.
- `einops`: torch tensor shaping with pretty api.
### DeVRF dataset
We release all the synthetic and real-world DeVRF dataset on [link](https://drive.google.com/drive/folders/1IuYCTIcUJxPJs6fE9SKSlLPNGiWs3OaQ?usp=sharing). DeVRF dataset consists of 5 inward-facing synthetic scenes (lego|floating_robot|kuka|daisy|glove), 1 inward-facing real-world scene (flower_360), and 3 forward-facing real-world scenes (plant|rabbit|pig_toy). For each scene, we release the static data, dynamic data, and optical flow estimated using [RAFT](https://github.com/princeton-vl/RAFT). Please refer to the following data structure for an overview of DeVRF dataset.

We additionally provide a light version of DeVRF dataset without optical flow on [link](https://drive.google.com/drive/folders/18-1aRhFd7Z9ugZCOAZ9ZmHcoc9eaRBcg?usp=sharing).
## 🏋️️ Experiment
### Training
Stage 1: Train the static model using static scene data.
The static model part is almost the same as [DirectVoxGO](https://github.com/sunset1995/DirectVoxGO). The main difference is that we add an accumulated transmittance loss to encourage a clean background for forward-facing scenes. Please refer to [DirectVoxGO](https://github.com/sunset1995/DirectVoxGO) for more details.
Note: Please enlarge the world_bound_scale in config file to establish a larger bounding box for dynamic scene modelling in the second stage. For DeVRF dataset, the world_bound_scale parameter is set within [1.05, 2.0].
```bash
$ cd static_DirectVoxGO
$ python run.py --config configs/inward-facing/lego.py --render_test
```
Stage 2: Train the dynamic model using dynamic scene data and the trained static model.
```bash
$ cd ..
$ python run.py --config configs/inward-facing/lego.py --render_test
```
### Evaluation
To only evaluate the testset `PSNR`, `SSIM`, and `LPIPS` of the trained `lego` without re-training, run:
```bash
$ python run.py --config configs/inward-facing/lego.py --render_only --render_test \
--eval_ssim --eval_lpips_vgg --eval_lpips_alex
```
Use `--eval_lpips_alex` or `--eval_lpips_vgg` to evaluate LPIPS with pre-trained Alex net or VGG net.
### Render video
```bash
$ python run.py --config configs/inward-facing/lego.py --render_only --render_video
```
