Update

The image-adaptive filtering techniques used in the segmentation task can be found in our preprint paper.

"Improving Nighttime Driving-Scene Segmentation via Dual Image-adaptive Learnable Filters". [arxiv]

Installation

$ git clone https://github.com/wenyyu/Image-Adaptive-YOLO.git  
$ cd Image-Adaptive-YOLO  
# Require python3 and tensorflow
$ pip install -r ./docs/requirements.txt

Datasets and Models

PSCAL VOC RTTS ExDark
Voc_foggy_test & Voc_dark_test & Models: Google Drive, Baidu Netdisk (key: iayl)

Quick test

# put checkpoint model in the corresponding directory 
# change the data and model paths in core/config.py
$ python evaluate.py 

Train and Evaluate on the datasets

1. Download VOC PASCAL trainval and test data

$ wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtrainval_06-Nov-2007.tar
$ wget http://host.robots.ox.ac.uk/pascal/VOC/voc2012/VOCtrainval_11-May-2012.tar
$ wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtest_06-Nov-2007.tar

Extract all of these tars into one directory and rename them, which should have the following basic structure.

VOC           # path:  /home/lwy/work/code/tensorflow-yolov3/data/VOC
├── test
|    └──VOCdevkit
|        └──VOC2007 (from VOCtest_06-Nov-2007.tar)
└── train
     └──VOCdevkit
         └──VOC2007 (from VOCtrainval_06-Nov-2007.tar)
         └──VOC2012 (from VOCtrainval_11-May-2012.tar)
                     
$ python scripts/voc_annotation.py

2. Generate Voc_foggy_train and Voc_foggy_val dataset offline

# generate ten levels' foggy training images and val images, respectively
$ python ./core/data_make.py 

3. Edit core/config.py to configure

--vocfog_traindata_dir'  = '/data/vdd/liuwenyu/data_vocfog/train/JPEGImages/'
--vocfog_valdata_dir'    = '/data/vdd/liuwenyu/data_vocfog/val/JPEGImages/'
--train_path             = './data/dataset_fog/voc_norm_train.txt'
--test_path              = './data/dataset_fog/voc_norm_test.txt'
--class_name             = './data/classes/vocfog.names'

4. Train and Evaluate

$ python train.py # we trained our model from scratch.  
$ python evaluate.py   
$ cd ./experiments/.../mAP & python main.py 

5. More details of Preparing dataset or Train with your own dataset
   reference the implementation tensorflow-yolov3.

Train and Evaluate on low_light images

The overall process is the same as above, run the *_lowlight.py to train or evaluate.

Acknowledgments

The code is based on tensorflow-yolov3, exposure.
