Multi-modal Text Recognition Networks: Interactive Enhancements between Visual and Semantic Features

| paper |

Official PyTorch implementation for Multi-modal Text Recognition Networks: Interactive Enhancements between Visual and Semantic Features (MATRN).

This paper introduces a novel method, called Multi-modAl Text Recognition Network (MATRN), that enables interactions between visual and semantic features for better recognition performances.

Datasets

We use lmdb dataset for training and evaluation dataset. The datasets can be downloaded in clova (for validation and evaluation) and ABINet (for training and evaluation).

• Training datasets
  • MJSynth (MJ)
  • SynthText (ST)
  • WikiText
• Validation datasets
  • The union of the training set of ICDAR2013, ICDAR2015, IIIT5K, and Street View Text
• Evaluation datasets
  • Regular datasets
    • IIIT5K (IIIT)
    • Street View Text (SVT)
    • ICDAR2013: IC13_S with 857 images, IC13_L with 1015 images
  • Irregular dataset
    • ICDAR2015: IC15_S with 1811 images, IC15_L with 2077 images
    • Street View Text Perspective (SVTP)
    • CUTE80 (CUTE)
• Tree structure of data directory

Requirements

pip install torch==1.7.1 torchvision==0.8.2 fastai==1.0.60 lmdb pillow opencv-python

Pretrained Models

• Download pretrained model of MATRN from this link. Performances of the pretrained models are:

• If you want to train with pretrained visioan and language model, download pretrained model of vision and language model from ABINet (for training and evaluation).

Training and Evaluation

• Training

python main.py --config=configs/train_matrn.yaml

• Evaluation

python main.py --config=configs/train_matrn.yaml --phase test --image_only

Additional flags:

• --checkpoint /path/to/checkpoint set the path of evaluation model
• --test_root /path/to/dataset set the path of evaluation dataset
• --model_eval [alignment|vision|language] which sub-model to evaluate
• --image_only disable dumping visualization of attention masks

Acknowledgements

This implementation has been based on ABINet.
