conda create -y -n evtexture python=3.7

Run in Docker :clap:

Note: before running the Docker image, make sure to install nvidia-docker by following the official instructions.

[Option 1] Directly pull the published Docker image we have provided from Alibaba Cloud.
```
docker pull registry.cn-hangzhou.aliyuncs.com/dachunkai/evtexture:latest
```
[Option 2] We also provide a Dockerfile that you can use to build the image yourself.
```
cd EvTexture && docker build -t evtexture ./docker
```
The pulled or self-built Docker image containes a complete conda environment named evtexture. After running the image, you can mount your data and operate within this environment.
```
source activate evtexture && cd EvTexture && python setup.py develop
```
Test
1. Download the pretrained models from (Releases / Onedrive / Google Drive / Baidu Cloud(n8hg)) and place them to experiments/pretrained_models/EvTexture/. The network architecture code is in evtexture_arch.py.
  - EvTexture_REDS_BIx4.pth: trained on REDS dataset with BI degradation for $4\times$ SR scale.
  - EvTexture_Vimeo90K_BIx4.pth: trained on Vimeo-90K dataset with BI degradation for $4\times$ SR scale.

Download the preprocessed test sets (including events) for REDS4 and Vid4 from (Releases / Onedrive / Google Drive / Baidu Cloud(n8hg)), and place them to datasets/.
- Vid4_h5: HDF5 files containing preprocessed test datasets for Vid4.
- REDS4_h5: HDF5 files containing preprocessed test datasets for REDS4.
Run the following command:
- Test on Vid4 for 4x VSR:
```
./scripts/dist_test.sh [num_gpus] options/test/EvTexture/test_EvTexture_Vid4_BIx4.yml
```
- Test on REDS4 for 4x VSR:
```
./scripts/dist_test.sh [num_gpus] options/test/EvTexture/test_EvTexture_REDS4_BIx4.yml
```
  This will generate the inference results in results/. The output results on REDS4 and Vid4 can be downloaded from (Releases / Onedrive / Google Drive / Baidu Cloud(n8hg)).

Data Preparation

Both video and event data are required as input, as shown in the snippet. We package each video and its event data into an HDF5 file.

Example: The structure of calendar.h5 file from the Vid4 dataset is shown below.

calendar.h5
├── images
│   ├── 000000 # frame, ndarray, [H, W, C]
│   ├── ...
├── voxels_f
│   ├── 000000 # forward event voxel, ndarray, [Bins, H, W]
│   ├── ...
├── voxels_b
│   ├── 000000 # backward event voxel, ndarray, [Bins, H, W]
│   ├── ...

To simulate and generate the event voxels, refer to the dataset preparation details in DataPreparation.md.

Inference on your own video

:heart: Seeking Collaboration: For issues #6 and #7, our method can indeed perform inference on videos without event data. The solution is to use an event camera simulator, such as vid2e, to generate event data from the video, and then input both the video data and the generated event data into our model. This part, however, may require extensive engineering work to package everything into a script, as detailed in DataPreparation.md. We currently do not have enough time to undertake this task, so we are looking for collaborators to join us in this effort! :blush:
