Shape Robust Text Detection with Progressive Scale Expansion Network

Requirements

• Python 2.7
• PyTorch v0.4.1+
• pyclipper
• Polygon2
• OpenCV 3.4 (for c++ version pse)
• opencv-python 3.4

Introduction

Progressive Scale Expansion Network (PSENet) is a text detector which is able to well detect the arbitrary-shape text in natural scene.

Training

CUDA_VISIBLE_DEVICES=0,1,2,3 python train_ic15.py

Testing

CUDA_VISIBLE_DEVICES=0 python test_ic15.py --scale 1 --resume [path of model]

Eval script for ICDAR 2015 and SCUT-CTW1500

cd eval
sh eval_ic15.sh
sh eval_ctw1500.sh
