ScrollView problem

[Jingjing Lin]

I'm trying to use ScrollView to see how tesseract does segmentation internally, and get the below error. Anyone have any idea about what is happening? Thanks!

Do you have these files in same folder as ScrollView.jar: piccolo2d-core-3.0.jar, piccolo2d-extras-3.0.jar and jaxb-api-2.3.1.jar ?

[Jingjing Lin]

Yes they were in different folder. I moved them to the same folder and now the command stuck after

Is this because I'm running tesseract on a ubuntu server. So somehow the output cannot be viewed?

Description how to run Segmenter Debug Mode is described in wiki . Which version of tesseract you used? Did you compiled by yourself ScrollView.jar?

What does it mean that you run tesseract on ubuntu server? Is it headless system?

Thanks I'm aware of the wiki page. The tesseract I'm running is the newest version that was built from source less than one month ago. I did compile ScrollView.jar from by myself. And the system I'm running it on is a headless system, it's a Ubuntu 16.04

tesseract start server and open (java) window with debugging info. So IMO you can not run it in real headless system, because there is no way how to show graphical results.

But you can try to use tools like e.g. mobaxterm on windows that can start graphical program from linux server (I use it to e.g. for rasbery pi)
