by Ruofan Zhou, Sabine Süsstrunk

Dependencies

• Pytorch >= 0.4.0
• OpenCV
• NVIDIA GPU
• HDF5 (only for training)
• MATLAB （only for training)

Quick start (Demo)

In test_code folder, run the following command:

python demo.py

Training the network yourself

Step 1: prepare the dataset

Download DEPD dataset, prepare the patches and run training_code/kernel_estimation/getkernels.m in MATLAB.

Step 2: train a GAN on kernels

run training_code/kernel_generator/train.py.

Step 3: generate

run training_code/kernel_generator/generate.py.

Step 4: train the super-resolution network

run training_code/super-resolution/main.py.
