warped text lines

[haratron]

Does tesseract provide a way to dewarp warped text lines?

[Junmock Lee]

How about RIL_WORD or RIL_SYMBOL instead of RIL_TEXTLINE?

No, I want to dewarp the warped lines of a page of a book. The warped lines is due to perspective distortion (picture acquired with the camera of a mobile phone) and curvature of the book. RIL_WORD or RIL_SYMBOL wouldn't help with that.

You can use leptonica (tesseract dependancy) for this taks.

Have a look at e.g. function dewarpSinglePage.

Leptonica has several example programs in prog directory that has "dewarp" in filename - maybe this can help you too.
