CRNN

A TensorFlow implementation of https://github.com/bgshih/crnn

But what is a CRNN?

It is a Convolutional Recurrent Neural Network that can be used as an OCR

Requirements

• Tensorflow (tested with 1.8) pip3 install tensorflow
• Scipy pip3 install scipy

What training data was used?

All training data (200 000 examples) were generated using my other project https://github.com/Belval/TextRecognitionDataGenerator

To do the same, simply clone that project and do python3 run.py -c 200000 -w 1 -t 8. -t should be your processor thread count.

Pretrained model

Available in CRNN/save. Use python3 run.py -ex ../data/test --test --restore to test.

Results

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.

For fun, here are a list of words with their prediction:

Ground truth	Prediction	Image
retardates	retardates
pay-roller	poy-roler
rhizopodist	rhizospodist
theriacas	trenagas
semantically	semanticaly
dualistic	duaistic
high-flying	highi-fling
grossify	grsity
scutular	scutular
