TecoGAN Docker

This repository contains source code and materials for the TecoGAN project, i.e. code for a TEmporally COherent GAN for video super-resolution. Authors: Mengyu Chu, You Xie, Laura Leal-Taixe, Nils Thuerey. Technical University of Munich.

This repository so far contains the code for the TecoGAN inference and training. Data generation, i.e., download, will follow soon. Pre-trained models are also available below, you can find links for downloading and instructions below. The video and pre-print of our paper can be found here:

Additional Generated Outputs

Our method generates fine details that persist over the course of long generated video sequences. E.g., the mesh structures of the armor, the scale patterns of the lizard, and the dots on the back of the spider highlight the capabilities of our method. Our spatio-temporal discriminator plays a key role to guide the generator network towards producing coherent detail.

Running the TecoGAN Model

Below you can find a quick start guide for running a trained TecoGAN model. For further explanations of the parameters take a look at the runGan.py file.
Note: evaluation (test case 2) currently requires an Nvidia GPU with CUDA and Linux.

1. Install docker

On Ubuntu/Debian/Linux-Mint etc.:

sudo apt-get install docker.io
sudo systemctl enable --now docker

Instructions for other platforms: https://docs.docker.com/install/

2. Install the NVIDIA Container Toolkit

This step will only work on Linux and is only necessary if you want GPU support. As far as I know it's not possible to use the GPU with docker under Windows/Mac.

On Ubuntu/Debian/Linux-Mint etc.:

# Add the package repositories
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list

sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit
sudo systemctl restart docker

Instructions for other platforms: https://github.com/NVIDIA/nvidia-docker

3. Build the docker images

for e in docker/*
do
        dockerfile_name=$(basename $e)
        docker build --file $e . -t "$dockerfile_name"_image 
done

4. Start the docker container we just build

You only need to start either the CPU or the GPU docker container.

CPU version:

docker run -it --mount src=$(pwd),target=/TecoGAN,type=bind -w /TecoGAN tecogan_cpu_image bash

GPU version:

docker run --gpus all -it --mount src=$(pwd),target=/TecoGAN,type=bind -w /TecoGAN tecogan_gpu_image bash

5. Run the model

Run the following inside the docker container.

# Download our TecoGAN model, the _Vid4_ and _TOS_ scenes shown in our paper and video.
python3 runGan.py 0

# Run the inference mode on the calendar scene.
# You can take a look of the parameter explanations in the runGan.py, feel free to try other scenes!
python3 runGan.py 1 

# Evaluate the results with 4 metrics, PSNR, LPIPS[1], and our temporal metrics tOF and tLP with pytorch.
# Take a look at the paper for more details! 
python3 runGan.py 2

Train the TecoGAN Model

1. Prepare the Training Data

The training and validation dataset can be downloaded with the following commands into a chosen directory TrainingDataPath. Note: online video downloading requires youtube-dl.

# take a look of the parameters first:
python3 dataPrepare.py --help

# To be on the safe side, if you just want to see what will happen, the following line won't download anything,
# and will only save information into log file.
# TrainingDataPath is still important, it the directory where logs are saved: TrainingDataPath/log/logfile_mmddHHMM.txt
python3 dataPrepare.py --start_id 2000 --duration 120 --disk_path TrainingDataPath --TEST

# This will create 308 subfolders under TrainingDataPath, each with 120 frames, from 28 online videos.
# It takes a long time.
python3 dataPrepare.py --start_id 2000 --duration 120 --REMOVE --disk_path TrainingDataPath

Once ready, please update the parameter TrainingDataPath in runGAN.py (for case 3 and case 4), and then you can start training with the downloaded data!

Note: most of the data (272 out of 308 sequences) are the same as the ones we used for the published models, but some (36 out of 308) are not online anymore. Hence the script downloads suitable replacements.

2. Train the Model

This section gives command to train a new TecoGAN model. Detail and additional parameters can be found in the runGan.py file. Note: the tensorboard gif summary requires ffmpeg.

# Train the TecoGAN model, based on our FRVSR model
# Please check and update the following parameters: 
# - VGGPath, it uses ./model/ by default. The VGG model is ca. 500MB
# - TrainingDataPath (see above)
# - in main.py you can also adjust the output directory of the  testWhileTrain() function if you like (it will write into a train/ sub directory by default)
python3 runGan.py 3

# Train without Dst, (i.e. a FRVSR model)
python3 runGan.py 4

Run the the following outside of the docker container (you need to replace the logdir path):

# View log via tensorboard
tensorboard --logdir='ex_TecoGANmm-dd-hh/log'
