Results on test data

haze -> clear

Input	Output

Prerequisites

• Linux or OSX
• NVIDIA GPU + CUDA CuDNN (CPU mode and CUDA without CuDNN may work with minimal modification, but untested)
• For MAC users, you need the Linux/GNU commands gfind and gwc, which can be installed with brew install findutils coreutils.

Getting Started

Installation

• Install torch and dependencies from https://github.com/torch/distro
• Install torch packages nngraph, class, display

luarocks install nngraph
luarocks install class
luarocks install https://raw.githubusercontent.com/szym/display/master/display-scm-0.rockspec

• Clone this repo:

git clone https://github.com/junyanz/CycleGAN
cd CycleGAN

Data preparing

First, download the dataset

• Unpaired dataset: The dataset is built by ourselves, and there are all real haze images from website.

  10000 images: Address：Baidu cloud disk Extraction code：zvh6

  1000 images: Address：Baidu cloud disk Extraction code:47v9

• Paired dataset: The dataset is added haze by ourselves according to the image depth.

  Address: Baidu cloud disk Extraction code : 63xf

• Now, let's generate dehaze images:

DATA_ROOT=./datasets/test name=dehaze_pretrained model=one_direction_test phase=test loadSize=256 fineSize=256 resize_or_crop="scale_width" th test.lua

The test results will be saved to ./results/dehaze_pretrained/latest_test/index.html.

Train

• Download a dataset (e.g. zebra and horse images from ImageNet):

bash ./datasets/download_dataset.sh haze2dehaze

• Train a model:

DATA_ROOT=./datasets/haze2dehaze name=haze2dehaze_model th train.lua

• (CPU only) The same training command without using a GPU or CUDNN. Setting the environment variables gpu=0 cudnn=0 forces CPU only

DATA_ROOT=./datasets/dehaze2haze name=haze2dehaze_model gpu=0 cudnn=0 th train.lua

• (Optionally) start the display server to view results as the model trains. (See Display UI for more details):

th -ldisplay.start 8000 0.0.0.0

Test

• Finally, test the model:

DATA_ROOT=./datasets/haze2dehaze name=haze2dehaze_model phase=test th test.lua

The test results will be saved to a html file here: ./results/haze2dehaze_model/latest_test/index.html.

Model Zoo

Download the pre-trained models with the following script. The model will be saved to ./checkpoints/model_name/latest_net_G.t7.

Display UI

Optionally, for displaying images during training and test, use the display package.

• Install it with: luarocks install https://raw.githubusercontent.com/szym/display/master/display-scm-0.rockspec
• Then start the server with: th -ldisplay.start
• Open this URL in your browser: http://localhost:8000

By default, the server listens on localhost. Pass 0.0.0.0 to allow external connections on any interface:

th -ldisplay.start 8000 0.0.0.0

Then open http://(hostname):(port)/ in your browser to load the remote desktop.
