Usage:

Quick usage on your data:

To run KernelGAN on all images in <input_image_path>:

python train.py --input-dir <input_image_path>

This will produce kernel estimations in the results folder

Extra configurations:

--X4 : Estimate the X4 kernel

--SR : Perform ZSSR using the estimated kernel

--real : Real-image configuration (effects only the ZSSR)

--output-dir : Output folder for the images (default is results)
