handwritten OCR using Python

In any OCR engine, the program has to do the following (see this post for more info).

Detect image border.

Detect and crop each words (especially when working with English)

Preprocess the image.

Recognize the word using OCR engine.

Particularly when working with handwritten documents, the OCR engines may not be provided through existing python package like OCRmyPDF. In that case you would have to write a code that combines each steps using separate available packages on Github.

Handwritten OCR engines.

As far as I searched on the web, there are some codes on Github

Line level OCR

https://github.com/lamhoangtung/LineHTR

This one does not contain pretrained model

https://github.com/sushant097/Handwritten-Line-Text-Recognition-using-Deep-Learning-with-Tensorflow

This one also includes pretrained model.

This means that you need to detect the lines or words in the pictures

For this you can use OpenCV

See the following two posts for how you implement this steps.
