Super Resolution with ESRGAN

Victoria Harbour, Hongkong

Github Repository

Project Setup

This project uses the ESRGAN repository available on Github:

git clone https://github.com/mpolinowski/ESRGAN.git

And we will be using a pre-trained model that can be downloaded from:

Super Resolution with ESRGAN

Download the pre-trained model and place it inside the ./models folder.

Install Dependencies

This project uses PyTorch which offers a little wizard helping you setting everything up based on your System - for me this is Linux and Python 3.10. But make sure to use a PC that has a nVidia graphic card with CUDA support:

pip3 install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu113

This installs PyTorch with CUDA v11. To check which version you have installed on your system run nvcc --version.

Additionally, we will be using OpenCV:

pip3 install opencv-python glob2

Run Up-Sampling

The repository already comes with two low-resolution example images that we can use:

ESRGAN Super Resolution

We can run the following script included inside the repository to feed those images into our GAN and output the up-sampled images into the ./results folder:

python test.py

Results
