Shape Robust Text Detection with Progressive Scale Expansion Network

Requirements

• pytorch 1.1
• torchvision 0.3
• pyclipper
• opencv3

Update

20190401

1. add author loss, the results are compared in Performance

Download

resnet50 and resnet152 model on icdar 2015:

1. bauduyun extract code: rxjf

2. google drive

Data Preparation

follow icdar15 dataset format

img
│   1.jpg
│   2.jpg   
│		...
gt
│   gt_1.txt
│   gt_2.txt
|		...

Train

1. config the trainroot,testrootin config.py
2. use following script to run

python3 train.py

Test

eval.py is used to test model on test dataset

1. config model_path, data_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, gt_path, save_path in predict.py
2. use following script to predict

python3 predict.py

The project is still under development.

Performance

ICDAR 2015

only train on ICDAR2015 dataset with single NVIDIA 1080Ti
