• Release inference code and pretrained models.
• Update links to paper and project page.
• Provide a runtime environment Docker image.
• Release train code and training set.

<a name="installation"></a>Installation

1. Clone this repo using git:

   git clone https://github.com/sherrycattt/EvLowLight.git
   

2. Create environment:

   Option 1: Using pip

   cd EvLowLight
   conda create -n evlowlight python=3.8
   conda activate evlowlight
   pip install -r requirements.txt
   

   Option 2: Using docker

   docker run --runtime=nvidia --gpus all --ipc=host --network=host  --rm -it \
     --ulimit memlock=-1 --ulimit stack=67108864 \
     -v `pwd`/EvLowLight:/workspace \
     -v `pwd`/timelens:/datasets/timelens \
     sherrycat/evlowlight
   

   Note the installation is only compatible with Linux users.

<a name="inference"></a>Inference

We provide an example for inference, check options/**_option.yml for more arguments.

python inference.py -opt options/timelens_option.yml

<a name="data"></a>Data Preparation

We provide example test data converted from the TimeLens for demo, which can be downloaded from Link (extracted code: Y9CN). Please place the dataset in the ../datasets folder. The dataset structure should be organized as follows:

├── timelens
│   └── events
│       ├── paprika_1000_gain_control_02
│       │   ├── events.txt
│       │   └── timestamp.txt
│       ├── pen_03
│       │   ├── events.txt
│       │   └── timestamp.txt
│       ...
│   └── low
│       ├── paprika_1000_gain_control_02
│       │   ├── 000000.png
│       │   └── 000001.png
│       │   ...
│       ├── pen_03
│       │   ├── 000000.png
│       │   └── 000001.png
│       │   ...
│       ...
│  ...

Each subfolder in the low folder contains image files with template filename %06d.png, and the file in the events subfolder contains events corresponding to the image subfolder with template filename events.txt defined as ev_file_ext in the option configuration file. Moreover, events also contains timestamp.txt where image timestamps are stored. The image stamps in timestamp.txt should match with the image files .
