A TensorFlow implementation of https://github.com/bgshih/crnn
It is a Convolutional Recurrent Neural Network that can be used as an OCR
- Tensorflow (tested with 1.8)
pip3 install tensorflow - Scipy
pip3 install scipy
All training data (200 000 examples) were generated using my other project https://github.com/Belval/TextRecognitionDataGenerator
To do the same, simply install that project with pip (pip install trdg) and do trdg -c 200000 -w 1 -t 8. -t should be your processor thread count.
Available in CRNN/save. Use python3 run.py -ex ../data/test --test --restore to test.
You can specify charset to include only numbers python run.py --train -ex ../data/test -it 50000 -cs 0123456789
It works but is a suboptimal solution for OCR in its current form as it makes some mistakes. Do note that I used a bigger char vector than the paper.
