OCR is an old problem. There is commercial software, such as Finereader, and free software such as Tesseract. But is there also a new trend in home-built software based on new frameworks for neural networks and deep learning? Keras? TensorFlow? Is anybody experimenting with this for OCR of scanned books?
When I ask researchers in image processing / computer vision, they say that plain text (book) OCR "is a solved problem" that nobody researches, and all research goes into self-driving cars reading street signs. Is this true, or are there any exceptions?
Yes. The recent tesseract is doing good on OCR. It uses machine learning technologies to train and giving better results with recent versions.
We have its improved proprietary version as google vision api, which provides little better results sometimes.
Here is a implementation of connecting wikisource and OCR via google drive. ( wrote this on 2015) https://github.com/tshrinivasan/OCR4wikisource
We used it many indic wikisource sites around 2016-2020.
