Nuxeo-Platform-OCR Question

Hi:

I'm trying to install 'Nuxeo-platform-ocr' (https://github.com/nuxeo/nuxeo-platform-ocr) , but I do not know where to locate the file 'content_in_doc', so that Nuxeo can use to analyze.

I have followed this manual https://github.com/nuxeo/nuxeo-platform-ocr, but not clear where to locate.

I'm using Ubuntu 10.11 + Tesseract + 3 + Nuxeo Olena (scribe)

Could you tell me where I locate the file 'content_in_doc'?

Thanks, and regards.

Olena is now available as deb packages for Debian and Ubuntu : http://www.lrde.epita.fr/cgi-bin/twiki/view/Olena/Download

Once installed, content_in_doc binary is located in /usr/lib/scribo/

Thanks for the info. I ve get this package and the content_in_doc is now working. Now I can get the plugin to work under Nuxeo 5.6, I will try again with Nuxeo 5.4.2 in order to see if the problem is generated by the changes introduced with 5.6

Configurations from nuxeo, for example ... If you have a component under nuxeo this is good but my customer want to configure every aspect directly from nuxeo

Sorry, I was not so clear in my previous post. Last year I was able to get this pluging worl¿king under Nuxeo 5.4.2 in an Oracle Linux installation. Then, I was trying to use the plugin in Nuxeo 5.5 under Ubuntu with the situation described above.

With the realease of Nuxeo 5.6 I decide to make a fresh installation under Ubuntu, and I was having troubles to get the content_in_doc binary. With Guillaume suggestion to use de new Olena package (thanks Guillaume!) I can get the file.

But when I try to use the OCR plugin, I get the same situation that under 5.5: he content_in_doc command is working fine. I try to convert an image from the commands lines and it works.

When I upload an image to Nuxeo, I can see a process like this running:

nuxeo 17203 17198 0 00:23 pts/0 00:00:00 content_in_doc /var/lib/nuxeo/server/tmp/cmdLineBasedConverter2216478922130777180.JPG /var/lib/nuxeo/server/tmp/ocr_olena_1355109823244.xml

And the file ocr_olena_xxxxxxx.xml is created under $NUXEO_HOME/tmp

But..... no annotations are generated in the document in Nuxeo"

And no errors are generated in server.log. This is all the information the log register after I do an upload: 2012-12-10 00:34:16,310 INFO [it.tidalwave.image.op.ReadOp] readMetadata(java.io.FileInputStream@705d5338, 0) 2012-12-10 00:34:16,319 INFO [it.tidalwave.image.op.ReadOp] read(java.io.FileInputStream@44f4660b, 0) 2012-12-10 00:34:17,438 DEBUG [com.hp.hpl.jena.shared.LockMRSW] Lock : Nuxeo-Work-default-4 2012-12-10 00:34:17,439 DEBUG [com.hp.hpl.jena.shared.LockMRSW] Nuxeo-Work-default-4 >> enterCS: Thread R/W: 0/0 :: Model R/W: 0/0 (thread: Nuxeo-Work-default-4) 2012-12-10 00:34:17,439 DEBUG [com.hp.hpl.jena.shared.LockMRSW] Nuxeo-Work-default-4 << enterCS: Thread R/W: 1/0 :: Model R/W: 1/0 (thread: Nuxeo-Work-default-4) 2012-12-10 00:34:17,440 DEBUG [com.hp.hpl.jena.shared.LockMRSW] Nuxeo-Work-default-4 >> leaveCS: Thread R/W: 1/0 :: Model R/W: 1/0 (thread: Nuxeo-Work-default-4) 2012-12-10 00:34:17,441 DEBUG [com.hp.hpl.jena.shared.LockMRSW] Nuxeo-Work-default-4 << leaveCS: Thread R/W: 0/0 :: Model R/W: 0/0 (thread: Nuxeo-Work-default-4)

Any suggestion to get the OCR plugin to work under NUxeo 5.6?

Does the XML file produced by content_in_doc contain anything ? Sometimes, if the document has a poor quality, content_in_doc may produce an empty file... 🙂

Yes, for example, the image: link text

Produces the following xml file in $NUXEO_HOME/server/tmp (I only reproduces some lines)

File: ocr_olena_1355615432288.xml

Hi @rbahntje i was facing the same problem $NUXEO_HOME/server/tmp/ocr_olena_xxx.xml was generated succesfuly but no annotations. After a few days a sloved this by editing code at github and now it works fine in production. I have create a pull request at https://github.com/nuxeo/nuxeo-platform-ocr/pulls describing the problem and solution.
