Re: [tesseract-ocr] Stop OCRing

[Zdenko Podobny]

Have a look at the ETEXT_DESC *monitor (e,.g. [1]). It is usually used for
getting progress monitor (e.g. [2] ), but should be used for cancelling
progress too according header file.

Re: [tesseract-ocr] Tesseract cannot read text on stripe background / but Google AI can

[Ajinkya Bobade]

Hello,
I have created a web extension which solves this problem. Upload image to
https://imagescanner-online.com/  it will clear your noise and
pixel-segment text so that you get a very good quality input, which you can
feed to tesseract and get good output

[Саша Карпюк]

Hello everybody. 
I work on Android and use Tesseract. 
Is exist any way to stop OCRing? For example, if I set bitmap to 
TessBaseApi and called getUTF8Text() method - can I stop this procces in 
another thread?
