Hello I need to make an OCR application, that can recognise birth dates, for example: "John, Smith" "02/01/2011" "John, Smith, 34 YO DOB 06Jan1981" I have these texts in a clean, cropped image (solid background), and on the image is just this text. All of the text is written in Arial, either 11px or 20px font size.
I have got 2 questions about the OCR: 1. I've read that tesseract is bad for recognising small text. What can i do to make the recongition better? Enlarge the images? use some filters on it? (I've tried enlarging, but the results were not so good, like 30% fail rate) 2. What would help the recognising process? Should i train tesseract for a custom language? (this is the only kind of 'setting' i read in the docs) Or is there some kind of supervised learning procedure for tesseract? I figured out, that i can whitelist characters with the command tessedit_char_whitelist , but i cant find a list of other config options or their meanings Thanks for help, i am really clueless how to get started with this project because of the lack of documentation. -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
