Subject [jira] [Commented] (TIKA-2261) TikaOcr giving different result across platforms
Date Wed, 08 Feb 2017 19:02:42 GMT

    [ https://issues.apache.org/jira/browse/TIKA-2261?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15858405#comment-15858405

Tim Allison commented on TIKA-2261:
-----------------------------------

Is there a chance that you have {{rotation.py}} or {{ImageMagick}} on the Mac but not Ubuntu?
 These preprocess the image before sending them to Tesseract if you have them installed.

> Hi,
> I am using Tika to parse every type of file and it works great for non image files. 
> My local machine is an Mac but I deploy stuff on ubuntu 14.04. On command line, i get
the same result on both the platforms.
> Example Command
> tesseract 3.jpg ouput -l eng -psm 1 txt
> But when I use it through Java code, it gives me very different results and the quality
is worse in case of ubuntu.
> Sample Code
>         AutoDetectParser parser = new AutoDetectParser();
>         BodyContentHandler handler = new BodyContentHandler(-1);
>         Metadata metadata = new Metadata();
>         FileInputStream in = new FileInputStream(path);
>         parser.parse(in, handler, metadata);
>         parsedText = handler.toString();
> On Mac :
> ++++++
> $ tesseract -v
> tesseract 3.04.01
>  leptonica-1.74.1
>   libjpeg 8d : libpng 1.6.28 : libtiff 4.0.7 : zlib 1.2.8
> On Ubuntu
> ubuntu@ubuntu-4gb-postprocess:~$ tesseract -v
> tesseract 3.04.01
>  leptonica-1.74.1
>   libjpeg 8d : libpng 1.6.28 : libtiff 4.0.7 : zlib 1.2.8
> Not able to figure out what the issue is. \
