Super Resolution Examples
We run this script under TensorFlow 2.0 and the TensorLayer 2.0+. For TensorLayer 1.4 version, please check release.

Prepare Data and Pre-trained VGG
-
- You need to download the pretrained VGG19 model in here as tutorial_models_vgg19.py show.
-
- You need to have the high resolution images for training.
- In this experiment, I used images from DIV2K - bicubic downscaling x4 competition, so the hyper-paremeters in
config.py
(like number of epochs) are seleted basic on that dataset, if you change a larger dataset you can reduce the number of epochs. - If you dont want to use DIV2K dataset, you can also use Yahoo MirFlickr25k, just simply download it using
train_hr_imgs = tl.files.load_flickr25k_dataset(tag=None)
inmain.py
. - If you want to use your own images, you can set the path to your image folder via
config.TRAIN.hr_img_path
inconfig.py
.
Run
- Set your image folder in
config.py
, if you download DIV2K - bicubic downscaling x4 competition dataset, you don't need to change it. - Other links for DIV2K, in case you can't find it : test_LR_bicubic_X4, train_HR, train_LR_bicubic_X4, valid_HR, valid_LR_bicubic_X4.
config.TRAIN.img_path = "your_image_folder/"
- Start training.
python train.py
- Start evaluation.
python train.py --mode=evaluate
