Training ocropus for handwritten text

[Subhodeep Maji]

Hi I am new to ocropus and i have read that ocropus can be used for handwritten text detection. I tried it but the results were a bit bad, is there a way to train ocropus for better results or can i get better results by changing some inputs(parameters and image) ?

I guess you would need a lot of training data (images+ground truth) and train a new model for your handwritting with that. I don't know of anyone has done much into this direction with ocropus. There might be other software/projects more tailored for handwritten text, e.g. https://transkribus.eu/Transkribus/ .

Thank you philipp for replying. I saw transkribus and found that it is a GUI based software and is not open source. I want something which has APIs and is open source for the kind of project i am doing. Also, as far as i understand we can train ocropus only for certain hand writings right ? I want something which is universal which may or may not require training. Once again thank you.

You are right however that OCR engines are not open source.
