Prepare code:

%cd /content
!git clone https://github.com/chaofengc/PSFR-GAN.git

%mkdir -p /content/PSFR-GAN/pretrain_models
%cd /content/PSFR-GAN/pretrain_models

Prepare data:

%cd /content/PSFR-GAN

url = 'https://i.imgur.com/7gPVDg4.png'
!wget {url}

from pathlib import Path
test_img_path = Path(url).name

Run:

%cd /content/PSFR-GAN
!python test_enhance_single_unalign.py \
 --test_img_path {test_img_path} \
 --results_dir results \
 --gpus 1

Export:

!tar czvf PSFRGAN.tar.gz /content/PSFR-GAN/results

I put this

%cd /content/PSFR-GAN
from google.colab import files
uploaded = files.upload()
test_img_path = 'X&A family2.png'

After

%cd /content/PSFR-GAN
!python test_enhance_single_unalign.py
--test_img_path {test_img_path}
--results_dir results
--gpus 1

And gave me this error

I think the problem are the spaces and the "&" in the filename.

Yes, it works now are the spaces, thks

I have a question, maybe you can help me

I have some images of a face with very poor quality, I have tried it and it comes out horrible,

I have many images of that person's face in very good quality.
My question is the following, is there a way to train the program so that on the good quality images of the face, then it knows how to interpret them with the poor quality one?

Considering that it is the same face.

I do not know if I explained well.
Thks

I have not done it, so I can only give a few hints here:

• there is a training procedure on your own data at https://github.com/chaofengc/PSFRGAN#train-script-for-psfrgan
• it is better to ask questions about training to the authors at https://github.com/chaofengc/PSFRGAN/issues

Ideally, you would want to fine-tune the pre-trained model with your data. I guess you need to use --continue_train.

I wrote to Chaofeng and reference to this links that's just i wanted The problem is that it's in Lua, and i don't know how to use it with windows 10 I send you this information, in case it may be of interest to you "Thanks for your interest. As for your problem, you may refer to reference based face SR: - https://github.com/csxmli2016/GFRNet - https://github.com/csxmli2016/ASFFNet Best, Chaofeng" El vie, 14 ene 2022 a las 8:44, Wok ***@***.***>) escribió:

Thank you, this is interesting. Chaofeng pointed to relevant repositories for your objective:

• csxmli2016/GFRNet at ECCV 2018: this looks like your problem of interest,
• csxmli2016/ASFFNet at CVPR 2020: this repository does not have public code, and it does not look like it will ever have.

Maybe you can find other recent papers or open-source repositories which would cite these papers.
From there, maybe you would be able to find software implementations in the programming languages which you are more accustomed with.

Sadly, I cannot help you with these.
