This is the implementation of our WACV 2019 paper "Gated Context Aggregation Network for Image Dehazing and Deraining" by Dongdong Chen, Mingming He, Qingnan Fan, et al.

In this paper, we propose a new end-to-end gated context aggregation network GCANet for image dehazing, in which the smoothed dilated convolution is used to avoid the gridding artifacts and a gated subnetwork is applied to fuse the features of different levels. Experiments show that GCANet can obtain much better performance than all the previous state-of-the-art image dehazing methods both qualitatively and quantitatively

We further apply our proposed GCANet to the image deraining task, which also outperforms previous state-of-the-art image deraining methods and demonstrates its generality.

This paper is implemented with Pytorch framework.

Directly put all your test images under one directory. Then run:

python test.py --task [dehaze | derain] --gpu_id [gpu_id] --indir [input directory] --outdir [output directory]

You can use our codes for research purpose only. And please cite our paper when you use our codes.
