Model can be downloaded from here

python compute_kernels.py -i image_path -m model_path

python image_deblurring.py -b blurry_img_path --reblur_model model_path --output_folder results

Additional options:
--blurry_images: may be a singe image path or a .txt with a list of images.

--n_iters: number of iterations in the RL optimization (default 30)

--resize_factor: input image resize factor (default 1)

--saturation_method: 'combined' or 'basic'. When 'combined' is passed RL in the presence of saturated pixels is applied. Otherwise, simple RL update rule is applied in each iteration. For Kohler images, 'basic' is applied. For RealBlur images 'combined' is better.

--gamma_factor: gamma correction factor. By default is assummed gamma_factor=2.2. For Kohler dataset images gamma_factor=1.0.
