Data Preparation

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

/path/to/img.jpg path/to/label.txt
...

val: use a folder

img/ store img
gt/ store gt file

Train

  1. config the train_data_path,val_data_pathin config.json
  2. use following script to run
python3 train.py

Test

eval.py is used to test model on test dataset

  1. config model_path, img_path, gt_path, save_path in eval.py
  2. use following script to test
python3 eval.py

Predict

predict.py is used to inference on single image

  1. config model_path, img_path, in predict.py
  2. use following script to predict
python3 predict.py

The project is still under development.
