Howdy.... I am wondering if anyone can help me get up and running on
ubuntu 9.1. I have a company that has some customized IT, we run some
custom-made software packages for my company on our servers, I'm
wondering if there's a chance this OCR package could be useful to us,
if so I may ask our IT people to look at integrating it into some
tools we use. There is definitely potential for us to contribute back
to the project if we wind up using it. I myself used to be a hobbyist
computer programmer until around 1995, after which I didnt have any
time for it.
Anyway, sorry for all the irrelevant babble. I have a VMware "virtual
applicance" image of ubuntu 9.1 desktop version which I downloaded
from the operating systems section of the virtual appliance
marketplace section of VMware's website. I installed ocropus on that
virtual Ubuntu applicance which appeared to go without a hitch, though
frankly there are one or two errors which appeared to be non-fatal and
which I shall profusely apologize, I didn't copy down.
At any rate, I have ocropus fully up and running, but it always comes
up with garbage whatever I throw at it, whether with the one-line page
command or the book2lines,etc., sequence of commands which is
recommended.
My questions:
(1) Does it come out-of-the-box trained on a recognition model, or is
it necessary to train it on a model to get it to work?
(2) When I test it out-of-the-box on a sample document that contains
what I think is easily recognizable test, I get this:
d...@ubuntu:~/ocropus$ ocropus page test.png

Question: Am I doing something wrong? I dont understand why the
results of ocropus page are so garbagey. I see a few places where
there are 3 characters in a row I suspect may have been correctly
identified.
Should I be able to run it right out of the box, following the install
instructions, and running it using the page option immediately?
The VMware appliance is running on a 2.4 ghz core 2 duo mac running os
10.6.2, vmare v 3.02
