Introduction

This repository contains the official implementations of PSENet, PAN, PAN++.

Text Detection

• PSENet (CVPR'2019)
• PAN (ICCV'2019)
• FAST (Arxiv'2021)

Text Spotting

• PAN++ (TPAMI'2021)

Installation

First, clone the repository locally:

git clone https://github.com/whai362/pan_pp.pytorch.git

Then, install PyTorch 1.1.0+, torchvision 0.3.0+, and other requirements:

conda install pytorch torchvision -c pytorch
pip install -r requirement.txt

Finally, compile codes of post-processing:

# build pse and pa algorithms
sh ./compile.sh

Dataset

Please refer to dataset/README.md for dataset preparation.

Training

CUDA_VISIBLE_DEVICES=0,1,2,3 python train.py ${CONFIG_FILE}

For example:

CUDA_VISIBLE_DEVICES=0,1,2,3 python train.py config/pan/pan_r18_ic15.py

Testing

Evaluate the performance

python test.py ${CONFIG_FILE} ${CHECKPOINT_FILE}
cd eval/
./eval_{DATASET}.sh

For example:

python test.py config/pan/pan_r18_ic15.py checkpoints/pan_r18_ic15/checkpoint.pth.tar
cd eval/
./eval_ic15.sh

Evaluate the speed

python test.py ${CONFIG_FILE} ${CHECKPOINT_FILE} --report_speed

For example:

python test.py config/pan/pan_r18_ic15.py checkpoints/pan_r18_ic15/checkpoint.pth.tar --report_speed

Visualization

python test.py ${CONFIG_FILE} ${CHECKPOINT_FILE} --vis

For example:

python test.py config/pan/pan_r18_ic15.py checkpoints/pan_r18_ic15/checkpoint.pth.tar --vis
