repository changes

[Tom]

The code refactoring is finally nearing an end and the next release is getting closer and closer.

Part of that is some repository changes.  The toplevel "ocropus" repository now is a repository containing subrepositories.  You should be able (on a recent Ubuntu system) to type:

hg clone https://code.google.com/p/ocropus ocropus

cd ocropus

sudo sh install-ubuntu-packages

sh compile-ocropus

If you still need access to the old ocropus repository, you can pull from https://code.google.com/p/ocropus.ocroold

Thanks for this.
I used ver 0.4 for my final year dissertation to recognise handwritten
historical documents (Gearge Washington's handwriting) but wasn't
successful at creating a good character model so recognition rate was
close to nil. I had split each word as separate images and had the
corresponding ground truth but didn't have enough knowledge of the
ocropus libraries to create cseg files for ultimate extraction of
chararacters. I plan to give it another go with the new version.

Cheers

Apparently not quite functional yet, though. I just did the above on
a 10.04 system, and tried running a page through:

% ocropus-pages /tmp/cleaned.png
/usr/lib/pymodules/python2.6/matplotlib/backends/backend_gtk.py:621:
DeprecationWarning: Use the new widget gtk.Tooltip
self.tooltips = gtk.Tooltips()

Whoops! That's from my old install. The latest fails like this:

% ocropus-lattices cleaned.png
# gcc -g -O4 -lm -shared -fopenmp -std=c99 -fPIC .pynative/
73fa8ca7cf53b3733eb77b5f1798ddb2.c -o .pynative/
73fa8ca7cf53b3733eb77b5f1798ddb2.so

Traceback (most recent call last):

File "/usr/local/bin/ocropus-lattices", line 84, in extract
lattice,rseg = linerec.recognizeLineSeg(image)

line 273, in recognizeLineSeg
raise RecognitionError("line image too high (maybe
rescale?)",image=image)

What's up here? Clearly segrec doesn't import RecognitionError from
common.
