Only use the Line-Detection of Tesseract

[dũng lê]

Hello everyone,

I only want to use the Line-Detection Module of Tesseract, not the Word Detection Module or Character Classification Module.

How can I do it ?

Thanks,

[Zdenko Podobny]

Can you please elaborate what do you mean by Line-Detection Module of Tesseract/Word Detection Module/Character Classification Module?

What did you do, and what do you want to achieve?

I read from this paper of Google about Tesseract:
https://research.google.com/pubs/archive/33418.pdf

So I only want to use this module, then I will use my module to recognize, not the module of Tesseract 

Thanks

I am still not sure if I understand you correctly but:

1. This is a very old document.

2. IMO you would like to use the document to analyze part of the tesseract only.

So have a look at API examples[1] for getting Result iterator and GetComponentImages examples. PageIteratorLevel helps you get the level (Block, Paragraph, Line, Word, Symbol) you are interested in.

And of course have a look at other API functions that can be useful for your project (e.g. GetTextlines, GetRegions...)
