Image Deblurring using Generative Adversarial Networks

DeblurGAN

arXiv Paper Version

Pytorch implementation of the paper DeblurGAN: Blind Motion Deblurring Using Conditional Adversarial Networks.

Our network takes blurry image as an input and procude the corresponding sharp estimate, as in the example:

The model we use is Conditional Wasserstein GAN with Gradient Penalty + Perceptual loss based on VGG-19 activations. Such architecture also gives good results on other image-to-image translation problems (super resolution, colorization, inpainting, dehazing etc.)

How to run

Prerequisites

• NVIDIA GPU + CUDA CuDNN (CPU untested, feedback appreciated)
• Pytorch

Download weights from Google Drive . Note that during the inference you need to keep only Generator weights.

Put the weights into

/.checkpoints/experiment_name

To test a model put your blurry images into a folder and run:

python test.py --dataroot /.path_to_your_data --model test --dataset_mode single --learn_residual

Data

Download dataset for Object Detection benchmark from Google Drive

Train

If you want to train the model on your data run the following command to create image pairs:

python datasets/combine_A_and_B.py --fold_A /path/to/data/A --fold_B /path/to/data/B --fold_AB /path/to/data

And then the following command to train the model

python train.py --dataroot /.path_to_your_data --learn_residual --resize_or_crop crop --fineSize CROP_SIZE (we used 256)
