I have a java based application running on Ubuntu 13.04 , but sikuli fails to extract the exact text !

Currently there are no options in this direction.

... it either works or not :-(

At least this: The region, where the text should be read, should be as narrow as possible and should contain only one line of text.
You might check the bad reads for some rules, that you can compensate.

If you have a chance to somehow change the font of the running app ( at least make it larger),then this might help.

Hi RaiMan ,

Thanks for your prompt reply , I really appreciate that !

Here are some more queries for you and my observation after testing the app using sikuli :

1] ... it either works or not :-(
Any thoughts on standard (or specific) font that sikuli renders accurate?

2] You might check the bad reads for some rules, that you can compensate.
After testing , I have observed that text rendering is accurate if we avoid combination of numbers,characters like '_' or '-' and uppercase.

Thanks again for your help.

standard serif or sans-serif fonts should normally work with a font size >= 12 and <= ??? (not tested)
when converting the test region to greyscale, the higher the contrast between background and text the better the result
... but one has always to check currently

yes ;-)

... and you might find, that in some cases either some spaces are ignored or even one is inserted where you do not expect one
