Olena 2.1 released
by Roland Levillain 08 Jul '14

08 Jul '14

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: http://olena.lrde.epita.fr/Olena210 You can download packages of the Olena 2.1 distribution here: http://www.lrde.epita.fr/dload/olena/2.1/olena-2.1.tar.gz (50 MB) http://www.lrde.epita.fr/dload/olena/2.1/olena-2.1.tar.bz2 (37 MB) The SHA1 digests of theses packages are: bae986faa08c908bd0e167e96c168033a53b5b47 olena-2.1.tar.gz 54f756b033a45d4c2fe1233c10fc43f99f9f552f olena-2.1.tar.bz2 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.

Formatting issue with 'Download' page

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. -- Fabien Freling ☛ http://www.ffreling.com ☎ +33 6 21 54 47 23

No executables after building from source on Ubuntu
by Remon Georgy 30 Jan '14

30 Jan '14

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.

Possible memory leak in scribo :: content_in_doc
by Remon Georgy 30 Oct '13

30 Oct '13

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

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. -- Armand Leclercq EPITA 2013 Assistant C/Unix

API Doc or Code samples
by Remon Georgy 22 Oct '13

22 Oct '13

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
