Tensorflow implementation of LapSRN algorithm described in [1]. It can now support training for 2x, 4x, and 8x scaling factor.

To run the training:

1. Download training dataset (DIV2K [2] [3])
   bash download_trainds.sh
2. Run the training for 4X scaling factor
   python main.py --train --scale 4
   or
   Set training images directory
   python main.py --train --scale 4 --traindir /path/to/dir

To run the test:
python3 main.py --test --scale 4
python3 main.py --test --scale 4 --testimg /path/to/image

To export file to .pb format:

1. Run the export script
   python3 main.py --export --scale 4
