Getting Started

Prerequisites

Tested environment

1. Environment setup

$ git clone https://github.com/codeslake/RealTime_VDBLR.git
$ cd RealTime_VDBLR

$ conda create -y --name RealTime_VDBLR python=3.8 && conda activate RealTime_VDBLR

# Install Pytorch (1.12.1 for example,)
$ conda install pytorch torchvision torchaudio cudatoolkit=11.6 -c pytorch -c conda-forge

# Install required dependencies (one of below depend on CUDA version)
# for CUDA10.2
$ ./install/install_CUDA10.2.sh
# for CUDA11.1
$ ./install/install_CUDA11.1.sh
# for CUDA11.3
$ ./install/install_CUDA11.3.sh
# for CUDA11.6
$ ./install/install_CUDA11.6.sh

2. Datasets

Download and unzip datasets under [DATASET_ROOT]:

• Su et al.'s DVD dataset: OneDrive | Dropbox
• Nah et al.'s GoPro dataset: OneDrive | Dropbox
• Nah et al.'s REDS dataset: download script

            ├── reds_valid
            └── reds_valid_gt

[DATASET_ROOT] can be modified with config.data_offset in ./configs/config.py.

3. Pre-trained models

Download pretrained weights (OneDrive | Dropbox) and place them under ./ckpt/:

Testing models of PG 2022

For PSNRs and SSIMs reported in the paper, we use the approach of Koehler et al. following Su et al., that first aligns two images using global translation to represent the ambiguity in the pixel location caused by blur.<br> Refer here for the evaluation code.

# [n]-stack MTUs evaluationed on [DVD|GoPro|REDS] datasets
./script_eval/MTU[n]_[dataset].py

# for 2-stack amp model,
./script_eval/MTU2_amp_[dataset].py

# for 10-stack large model,
./script_eval/MTU10_L_[dataset].py

# 4-stack model on REDS dataset, for example,
./script_eval/MTU4_REDS.py

Testing results will be saved in [LOG_ROOT]/PG2022_RealTime_VDBLR/[mode]/result/eval/[mode]_[epoch]/[data]/.

[LOG_ROOT] can be modified with config.log_offset in ./configs/config.py.

options

• --data: The name of a dataset to evaluate: DVD | nah | REDS. Default: DVD
  • The data structure can be modified in the function set_eval_path(..) in ./configs/config.py.
