How to run the project

  1. $pip install -r requirements.txt

We run this script under TensorFlow 1.4 and the TensorLayer 1.8.0+.

🚀 This repo will be moved to here (please star) for life-cycle management soon. More cool Computer Vision applications such as pose estimation and style transfer can be found in this organization.

Results

Prepare Data and Pre-trained VGG

    1. You need to download the pretrained VGG19 model in here as tutorial_vgg19.py show.
    1. 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) in main.py.
    • If you want to use your own images, you can set the path to your image folder via config.TRAIN.hr_img_path in config.py.

Run

config.TRAIN.img_path = "your_image_folder/"
  • Start training.
python main.py
python main.py --mode=evaluate
