Subject [jira] [Commented] (TIKA-93) OCR support
Date Tue, 07 Oct 2014 21:32:37 GMT

    [ https://issues.apache.org/jira/browse/TIKA-93?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14162577#comment-14162577

Tyler Palsulich commented on TIKA-93:

Hi [~twigbranch]. OCR is not currently run on embedded images by default. You can see an example
(in Java) of enabling OCR on embedded images in the TesseractOCRTest. So, tika-app currently
will only run OCR on direct image files. Have you tried that?

> I don't know of any decent open source pure Java OCR libraries, but there are command
line OCR tools like Tesseract (http://code.google.com/p/tesseract-ocr/) that could be invoked
by Tika to extract text content (where available) from image files.
