Multiple colours text in an image

[Iago Giné]

Hi all,

Is there some option to tell tesseract-ocr that there is text with multiple colours, so it detect all the text? For example, in my case, I have a pdf with the cover of a book, with yellow background and text both in black and also in white. Depending on how I proceed, I get only the text in black or the text in white, but not both.

I have only found the next issue, but no answer or anything more :https://github.com/tesseract-ocr/tesseract/issues/3078

Thank you for your time!

Iago

Hello,

this is about image preprocessing/thresholding rather than tesseract...

Please post an example image so tesseract users can test it and suggest a possible solution.
