STELA: A Real-Time Scene Text Detector with Learned Anchor

STELA is a simple and intuitive method for multi-oriented text detection based on RetinaNet. The key idea is utilizing the learned anchor which is obtained through a regression operation to replace the original into the final predictions. In our experiments, it achieves an F-measure 0.887 on ICDAR 2013, 0.833 on ICDAR 2015 and 0.715 on ICDAR 2017 MLT. For more details, please refer to our paper.

Installation

This code is modified from RetinaNet and maskrcnn-benchmark. It has been tested on Ubuntu 16.04 with CUDA 9.0 and PyTorch 1.1. If you have any issue, please leave a message.

0. Clone this repository

   git clone https://github.com/xhzdeng/stela.git
   

1. Build the Cython modules

   cd $STELA_ROOT/utils
   sh make.sh
   

2. Prepare your own data directory. For our implement, it should follow the format of PASCAL VOC.

3. Train with YOUR dataset

   cd $STELA_ROOT
   python train.py
   

4. Test with YOUR models

   cd $STELA_ROOT
   python eval.py
