update

2020-06-07: 添加灰度图训练，训练灰度图时需要在配置里移除dataset.args.transforms.Normalize

Install Using Conda

conda env create -f environment.yml
git clone https://github.com/WenmuZhou/DBNet.pytorch.git
cd DBNet.pytorch/

or

Install Manually

conda create -n dbnet python=3.6
conda activate dbnet

conda install ipython pip

# python dependencies
pip install -r requirement.txt

# install PyTorch with cuda-10.1
# Note that you can change the cudatoolkit version to the version you want.
conda install pytorch torchvision cudatoolkit=10.1 -c pytorch

# clone repo
git clone https://github.com/WenmuZhou/DBNet.pytorch.git
cd DBNet.pytorch/

Requirements

• pytorch 1.4+
• torchvision 0.5+
• gcc 4.9+

Download

TBD

Data Preparation

Training data: prepare a text train.txt in the following format, use '\t' as a separator

./datasets/train/img/001.jpg	./datasets/train/gt/001.txt

Validation data: prepare a text test.txt in the following format, use '\t' as a separator

./datasets/test/img/001.jpg	./datasets/test/gt/001.txt

• Store images in the img folder
• Store groundtruth in the gt folder

The groundtruth can be .txt files, with the following format:

x1, y1, x2, y2, x3, y3, x4, y4, annotation

Train

1. config the dataset['train']['dataset'['data_path']',dataset['validate']['dataset'['data_path']in config/icdar2015_resnet18_fpn_DBhead_polyLR.yaml

• . single gpu train

bash singlel_gpu_train.sh

• . Multi-gpu training

bash multi_gpu_train.sh

Test

eval.py is used to test model on test dataset

1. config model_path in eval.sh
2. use following script to test

bash eval.sh

Predict

predict.py Can be used to inference on all images in a folder

1. config model_path,input_folder,output_folder in predict.sh
2. use following script to predict

bash predict.sh

You can change the model_path in the predict.sh file to your model location.

tips: if result is not good, you can change thre in predict.sh

The project is still under development.

Performance

ICDAR 2015

only train on ICDAR2015 dataset

examples
