Installation

• Dependencies: Miniconda, CUDA Toolkit 11.1.1, torch 1.10.2+cu111, and torchvision 0.11.3+cu111.

• Run in Conda

  conda create -y -n evtexture python=3.7
  conda activate evtexture
  pip install torch-1.10.2+cu111-cp37-cp37m-linux_x86_64.whl
  pip install torchvision-0.11.3+cu111-cp37-cp37m-linux_x86_64.whl
  git clone https://github.com/DachunKai/EvTexture.git
  cd EvTexture && pip install -r requirements.txt && python setup.py develop

• Run in Docker 👏

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

  [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.

2. 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.

3. 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)).
