Intro

This repo re-produced paper including training codes. I wrote this codes from here, where you can only get the test code, and implemented traing parts following the paper as much as I can. Because some hyper-parameters, such as the number of channels for each layer in High-to-Low generator and discriminators, were missing in the paper, they were set by my own choice.

In the paper, they used the spectral normalization. The spectral normalization code used in here is adopted from repo.

In this repo, files with prefix yoon_ are additionally impelmantatied files to the authors' repo.

Requirements

Pytorch, Opencv, numpy, ...

Data

Running testing

CUDA_VISIBLE_DEVICES=0, python model_evaluation.py 

Fid Calculation

CUDA_VISIBLE_DEVICES=0, python fid_score.py /Dataset/HIGH/SRtrainset_2/ test_res/

This code is from https://github.com/mseitzer/pytorch-fid

Running training

python yoon_train.py --gpu [your_gpu_num]

You can replace [your_gpu_num] with a number (gpu id).

If your dataset folders are different from the default setting, you have to locate the folders using High_Data and Low_Data variables in yoon_data.py.
