Subject [jira] [Commented] (TIKA-2749) OCR on PDFs should "just work" out of the box
Date Sat, 06 Oct 2018 13:35:00 GMT

    [ https://issues.apache.org/jira/browse/TIKA-2749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16640724#comment-16640724

Luis Filipe Nassif commented on TIKA-2749:

Hi [~tallison@apache.org],

Yes, currently we run ocr (rendering the page) if there are less than 100 chars in the page.
Our main goal is to ocr scanned docs.

If we want Tika to ocr more content, maybe:

1) if < 10 words in the page, ocr the rendered page (blank pages are fast to ocr, so the
impact is minimal)

2) if >= 10 words in the page, ocr each extracted image

Maybe our pdfbox colleagues should be invited to join the discussion?

>            Reporter: Tim Allison
>            Priority: Major
> There are now two different ways (with various parameters) to trigger OCR on inline images
within PDFs.  The user has to 1) understand that these are available and then 2) elect to
turn one of those on.
> I think we should make OCR'ing on PDFs "just work" perhaps with a hybrid strategy between
the 2 options.  Users should still be allowed to configure as they wish, of course.
