Jukka Zitting commented on TIKA-93:
-----------------------------------
> are there any updates regarding this issue?
Not really. I've done some simple tests with ExternalParser invoking Tesseract
and OCRopus, but neither is really suited for simple OOTB integration.
I also tried the commercial Asprise OCR SDK
(http://asprise.com/product/ocr/index.php?lang=java) which was much easier to
set up and get reasonable results from, but obviously it's something that we
can't use in an Apache project.
If someone wants to help with this, the first step would be to come up with
reasonably simple steps to get a liberally licensed OCR engine like OCRopus
installed and configured so that you can invoke it using a simple command line
like "ocr image.gif" and get the extracted text on the standard output. It
should work for at least a few simple test cases. Note that this work should be
contributed back to the upstream project.
Once we have something like that, we can move forward with integrating it to
Tika.
