This is the code of "Mask TextSpotter: An End-to-End Trainable Neural Network for Spotting Text with Arbitrary Shapes" (TPAMI version). It is an extension of the ECCV version while sharing the same title. For more details, please refer to our TPAMI paper.

This repo is inherited from maskrcnn-benchmark and follows the same license.

  # first, make sure that your conda is setup properly with the right environment
  # for that, check that `which conda`, `which pip` and `which python` points to the
  # right path. From a clean conda env, this is what you need to do

  conda create --name masktextspotter -y
  conda activate masktextspotter

  # this installs the right pip and dependencies for the fresh python
  conda install ipython pip

  # python dependencies
  pip install ninja yacs cython matplotlib tqdm opencv-python shapely scipy tensorboardX

  # install PyTorch
  conda install pytorch torchvision cudatoolkit=10.0 -c pytorch

  export INSTALL_DIR=$PWD

  # install pycocotools
  cd $INSTALL_DIR

  cd apex
  python setup.py install --cuda_ext --cpp_ext

Download Trained model

You can run a demo script for a single image inference by python tools/demo.py.

Download the ICDAR2013(Google Drive, BaiduYun) and ICDAR2015(Google Drive, BaiduYun) as examples.

The SCUT dataset used for training can be downloaded here.

The converted labels of Total-Text dataset can be downloaded here.

The converted labels of SynthText can be downloaded here.

The root of the dataset directory should be MaskTextSpotter/datasets/.

An example of the path of test images: MaskTextSpotter/datasets/icdar2015/test_iamges

test dataset: TEST.DATASETS;

input size: ```INPUT.MIN_SIZE_TEST''';

model path: MODEL.WEIGHT;

output directory: OUTPUT_DIR

Place all the training sets in MaskTextSpotter/datasets/ and check DATASETS.TRAIN in the config file.

Trained with SynthText

python3 -m torch.distributed.launch --nproc_per_node=8 tools/train_net.py --config-file configs/pretrain.yaml

Trained with a mixure of SynthText, icdar2013, icdar2015, scut-eng-char, and total-text

check the initial weights in the config file.

python3 -m torch.distributed.launch --nproc_per_node=8 tools/train_net.py --config-file configs/finetune.yaml

download the lexicons and place them like evaluation/lexicons/ic15/

cd evaluation/icdar2015/e2e/
# edit "result_dir" in script.py
python script.py
