This is a demo using lstm and ctc to recognize a picture of a series numbers with blanks all at once. The code is compatible with Python3.
For example: given the piture below the model would give result 73791096754314441539.
# on mac
pip install pillow
pip install opencv-python
brew install cmake
brew tap homebrew/science
brew install opencv
sh ./prepare_train_data.sh
# on ubuntu
pip intall pillow
pip install opencv-python
pip install tensorflow-gpu
The prepare_train_data.sh script would download the SUN database and extract the pitures to bgs dir. Then you can run python gen.py to generate test and train dir.
When the train and test data set are ready you can start the train process by nohup python lstm_and_ctc_ocr_train.py .
