Hello,

I am trying to find working example of optical character recognition in deeplearning4j without any result. Have you ever seen that example or could you give me some advice how to prepare data to learn network to learn it predict text in image ? Thanks in advance for help

While the MultiDigitNumberRecognition is a good starting point, you should also remember that OCR in general isn’t an easy problem.

So you might also want to read about the tesseract project (e.g. docs/das_tutorial2016 at main · tesseract-ocr/docs · GitHub) and how they are training an lstm for OCR: https://github.com/tesseract-ocr/tessdoc/blob/master/TrainingTesseract-4.00.md
