The Olena Team is proud to announce the release of Olena 2.1.
Olena is a platform dedicated to image processing and pattern
recognition. Its core component is a generic and efficient C++
library called Milena. Milena provides a framework to implement
simple, fast, safe, reusable and extensible image processing tool
chains. The library provides many ready-to-use image data structures
(regular 1D, 2D, 3D images, graph-based images, etc.) and algorithms.
Milena's algorithms are built upon classical entities from the image
processing field (images, points/sites, domains, neighborhoods, etc.).
This design allows image processing developers and practitioners to
easily understand, modify, develop and extend new algorithms while
retaining the core traits of Milena: genericity and efficiency.
On top of Milena, the Olena platform also features optional modules
such as Swilena, a component exposing Milena to other languages thanks
to the Simplified Wrapper and Interface Generator (SWIG); and the
Scribo module for Document Image Analysis (see below).
The Olena platform is Free Software. It is distributed under the
conditions of the GNU General Public License (GPL) version 2. See the
file COPYING shipped with the Olena distribution.
Release notes are available at:

This version is mostly a ``fix-up'' release of Olena 2.0, containing
many corrections and improvements since the previous release.
Here is a list of major changes since Olena 2.0:
* New and improved algorithms (binarization, skeletonization, layout
analysis) and I/O routines (PDF, VTK).
* Minimal support for FFTW 3 (Fast Fourier Transform).
* The Scribo distribution now contains a Doxygen
documentation.
* Support for modern toolchains and especially recent C++ compilers
(GCC 4.8, Clang 3.5).
The file NEWS, milena/NEWS, scribo/NEWS and swilena/NEWS, included in
the archive, contain a more complete list of user-visible changes.

We work at the same lab where OLENA is developed, but Alfred and I are
not part of that team. I've taken the liberty of Cc'ing the appropriate
mailing list in this response of mine; I'm sure the people there will be
happy to address your concerns.
Best regards,

It seems that you recently updated the theme of the LRDE website.
It is quite nice, unfortunately it broke the formatting on the following
page:
https://www.lrde.epita.fr/wiki/Olena/Download
Not a proper bug per se, but it's unfortunate.

Hello,
I was trying to build Olena/Scribo from Git source, on Ubuntu 13.10. I made
sure to install all requirements in
https://www.lrde.epita.fr/wiki/Olena/Download#Getting_the_source_from_the_d…
well as couple of other requirements that showed up during building.
Configure, Make, Make install all run flawlessly, scribo-cli command seems
to is installed to /usr/local/bin/. However, all internal
executables/script are not installed in /usr/local/libexec/.
Attempting to run command will yield this output:
$ scribo-cli pic-ocr
/usr/local/bin/scribo-cli: line 122:
/usr/local/libexec/scribo/text_recognition_in_picture: No such file or
directory
It's my first time using the source from Git. I've previously built olena
from dist package olena-2.0a and it worked correctly on Mac OSX.
Please advise and let me know shall you need more details.
Thanks in advance.
Cheers,
Remon

Hello there,
I was trying Scribo module with multiple pictures, using either cli or
viewer version, I admit
it generates very good results!
However, I'm experiencing a memory leak with a *certain* image. It happens
in content_in_doc binary when I run scribo-cli as follows:
scribo-cli doc-dia input.png out.xml
Strangely enough I found that the command populates out.xml correctly! but
it never returns and it keeps on chewing memory VERY fast, like reaching
couple GB in few seconds.
I tried to disable optional toggles one by one to narrow down the suspect.
I found out that the leak doesn't happen if I add the option
--disable-find-seps.
Please find attached the single image that causes this leak as well as xml
output.
I'll try to trace it as much as a I can, any clues would be great, though.
Best regards,
Remon
Hi,
I like the look of olena and want to check it out. But I'm asked for a login for the sample code. e.g. neighborhood.cc
Any help appreciated

Hello,
I recently updated my system, and
g++ (Debian 4.8.1-10) 4.8.1
came in with.
With this new version, I got the following bug resolved:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33255
But it causes a lot of warning for my code using milena.
I propose the following patch that suppress the warnings from user code.

Hi,
I really admire Olena framework, specially Scribo module!
I've been using Tesseract for a while now, and layout analysis is not it's strongest feature.
Using Scribo to anaylze pictures and passing text regions to tesseract makes a lot of sense.
I want to get started with using Scribo in my C++ code, however, It would be grateful if their is
any kind of API docs to consult or some example programs that uses scribe API. I'd really appreciate
any pointers.
Keep up the excellent work!
Thanks in advance.
Remon
