+# AOD-Net
+
+ICCV 2017 
+
+AOD-Net is a light-weight but effective end-to-end dehazing neural network.
+
+
+It is very easy and fast for you to train or test.
+
+For test:
+
+We have offered test.py, relevant prototxt and data.
+You can just use 'python test.py' with GPU/CPU, you can obtain your result in data/result.
+
+Good luck for your research.
+
+# Improved AOD-Net with Positional Normalization (PONO)
+We appreciate the [PyTorch implementation](https://github.com/TheFairBear/PyTorch-Image-Dehazing) of AOD-Net. Based on this code, we add simple [PONO](https://github.com/Boyiliee/PONO) into AOD-Net, which improves the performance efficiently.
+
+Previous AOD-Net Results:

+
+For TestSet A, the PSNR increases from 19.69 to 20.38 dB, the SSIM increases from 0.8478 to 0.8587. For TestSetB, the PSNR increases from 21.54 to 21.67 dB, the SSIM increases from 0.9272 to 0.9285.

+Gated Context Aggregation Network for Image Dehazing and Deraining
+=======
+![image](imgs/net_arch.png)
+
+This is the implementation of our WACV 2019 paper *"Gated Context Aggregation Network for Image Dehazing and Deraining"* by [Dongdong Chen](<http://www.dongdongchen.bid/>), [Mingming He](<https://github.com/hmmlillian>), [Qingnan Fan](<https://fqnchina.github.io/>), *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
+![image](imgs/dehaze_visual.png)
+
+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.
+![image](imgs/derain_visual.png)
+
+
+## Getting Started
+
+This paper is implemented with Pytorch framework.
+
+Demo
+----
+
+Directly put all your test images under one directory. Then run:
+
+```bash
+python test.py --task [dehaze | derain] --gpu_id [gpu_id] --indir [input directory] --outdir [output directory]
+```
+
+For training, please download the training code from <https://drive.google.com/file/d/1T7X1HYztbz6S75vTRNtREgGEOI269KDk/view?usp=sharing>
+
+Cite
+----
+
+You can use our codes for research purpose only. And please cite our paper when you use our codes.

+# RefineDNet for dehazing
+
+RefineDNet is a two-stage dehazing framework which can be weakly supervised using real-world unpaired images. 
+That is, the training set never requires paired hazy and haze-free images coming from the same scene.
+
+In the first stage, it adopts DCP to restore visibility of the input hazy image. 
+In the second stage, it improves the realness of preliminary results from the first stage via CNNs. 
+RefineDNet is outlined in the following figure, and more details can be found in the [paper](https://doi.org/10.1109/TIP.2021.3060873) (or [this link](https://sse.tongji.edu.cn/linzhang/files/RefineDNet_TIP.pdf)) titled as _RefineDNet: A Weakly Supervised Refinement Framework for Single Image Dehazing._ (Early Access in Trans. Image Process.)

+
+2. Create a folder named `checkpoints`, and unzip `refined_DCP_outdoor.zip` in `./checkpoints`.
+Now, your directory tree should look like

+"""General-purpose training script for image-to-image translation.
+
+This script works for various models (with option '--model': e.g., pix2pix, cyclegan, colorization) and
+different datasets (with option '--dataset_mode': e.g., aligned, unaligned, single, colorization).
+You need to specify the dataset ('--dataroot'), experiment name ('--name'), and model ('--model').
+
+It first creates model, dataset, and visualizer given the option.
+It then does standard network training. During the training, it also visualize/save the images, print/save the loss plot, and save models.
+The script supports continue/resume training. Use '--continue_train' to resume your previous training.
+
+Example:
+    Train a CycleGAN model:
+        python train.py --dataroot ./datasets/maps --name maps_cyclegan --model cycle_gan
+    Train a pix2pix model:
+        python train.py --dataroot ./datasets/facades --name facades_pix2pix --model pix2pix --direction BtoA
+
+See options/base_options.py and options/train_options.py for more training options.

+# Dehaze 使用手册
+
+## 1. 项目用途
+
+本项目用于对 `待去雾图片/` 中的图片进行去雾，并在网页端统一展示以下方法的结果：
+
+- AOD
+- Baidu_API
+- DCP
+- DehazeNet
+- GCANet
+- RefineDNet
+- 后处理：手动 S/V、HSV 直方图匹配、自动 S/V、直方图匹配 + 自动 S/V
+
+## 2. 启动网页
+
+```bash
+cd /home/wkmgc/Desktop/Dehaze
+./run_dehaze_web.sh
+```
+
+浏览器访问：
+
+```text
+http://192.168.3.11:7860/
+```
+
+## 3. 环境说明
+
+当前项目使用统一网页服务调度不同模型环境：
+
+- Web、DCP、Baidu_API、后处理：当前 base Python
+- AOD、DehazeNet：`/home/wkmgc/miniconda3/envs/dehaze_caffe/bin/python`
+- GCANet、RefineDNet：`/home/wkmgc/miniconda3/envs/seg_server/bin/python`
+
+`run_dehaze_web.sh` 已默认配置这些解释器。如需换环境，可设置：
+
+```bash
+export DEHAZE_CAFFE_PYTHON=/path/to/caffe/python
+export DEHAZE_TORCH_PYTHON=/path/to/torch/python
+```
+
+## 4. 百度 API 配置
+
+真实密钥不要提交到 git。复制示例文件：
+
+```bash
+cp config/baidu_api.env.example config/baidu_api.env
+```
+
+填入：
+
+```text
+BAIDU_API_KEY=...
+BAIDU_SECRET_KEY=...
+```
+
+也可以在启动前直接设置环境变量。
+
+## 5. 使用流程
+
+1. 将待处理图片放入 `待去雾图片/`。
+2. 启动网页。
+3. 在左侧选择图片。
+4. 勾选需要运行的模型，点击“运行选中模型”。
+5. 在后处理区域选择源图、参考图和后处理方法，点击“生成后处理”。
+6. 结果会保存到 `web_results/`，网页会自动刷新显示。
+
+页面中“未生成”表示对应结果文件还不存在，并不是任务卡住。
+
+## 6. 命令行验证
+
+验证全部图片和全部模型：
+
+```bash
+python scripts/verify_all.py
+```
+
+如不想调用百度 API：
+
+```bash
+python scripts/verify_all.py --skip-baidu
+```
+
+只验证指定图片：
+
+```bash
+python scripts/verify_all.py --images 1.png
+```
+
+## 7. 清理生成物
+
+清理缓存和运行结果：
+
+```bash
+./scripts/clean_generated.sh
+```
+
+清理后重新启动网页并运行模型即可再生成结果。
+
+## 8. 目录说明
+
+- `web_dehaze/`：统一网页服务、模型调度和后处理代码。
+- `待去雾图片/`：待处理原图。
+- `web_results/`：网页运行生成结果，已加入 `.gitignore`。
+- `AOD-Net_最好加入后处理/`：AOD 模型与入口脚本。
+- `Baidu_API_最好加入后处理/`：百度去雾 API 脚本。
+- `DCP_最好加入后处理/`：DCP 去雾脚本。
+- `DehazeNet/`：DehazeNet 模型与入口脚本。
+- `GCANet/`：GCANet 模型与入口脚本。
+- `RefineDNet/`：RefineDNet 模型、权重与入口脚本。
+- `※程序-后处理汇总/`：原始后处理脚本归档。
