FSRCNN
This repository is implementation of the "Accelerating the Super-Resolution Convolutional Neural Network".
Differences from the original
- Added the zero-padding
- Used the Adam instead of the SGD
Requirements
- PyTorch 1.0.0
- Numpy 1.15.4
- Pillow 5.4.1
- h5py 2.8.0
- tqdm 4.30.0

Otherwise, you can use prepare.py to create custom dataset.
python train.py --train-file "BLAH_BLAH/91-image_x3.h5" \
--eval-file "BLAH_BLAH/Set5_x3.h5" \
--outputs-dir "BLAH_BLAH/outputs" \
--scale 3 \
--lr 1e-3 \
--batch-size 16 \
--num-epochs 20 \
--num-workers 8 \
--seed 123 Test
Pre-trained weights can be downloaded from the links below.

The results are stored in the same path as the query image.
python test.py --weights-file "BLAH_BLAH/fsrcnn_x3.pth" \
--image-file "data/butterfly_GT.bmp" \
--scale 3Results
PSNR was calculated on the Y channel.
