Salut tout le monde, j'ai voulu tester ce week-end la démo en ligne de dématérialisation ( http://olena.lrde.epita.fr/demos/document_segmentation.php) de document pour récupérer mon image en pdf mais ça a finit en erreur : "PDF output : /tmp/web_app147489430652208889c261d3.66045018.pdf"Ooops! Something went wrong. Please contact us in order to fix that! olena(a)lrde.epita.fr. Thank you! Ca fait la même chose si je lance la démo avec les images proposées sur le site. Je n'ai pas de problème par contre avec la démo sur les documents historiques. Bon courage et à bientôt. :) A+

SauvolaMs, for ancient Torah Scrolls Binarization ?
by Albert Berman 05 Sep '13

05 Sep '13

Shalom Olena team, At Ben-Gurion University in Israel we evaluating binarization approaches for ancient Torah Scrolls right now. You SauvoulaMS approach :"Efficient Multiscale Sauvola's Binarization". seems to be very accurate even despite of inhomogeneous background! So we would be really gad to use it and see how it performs ahead of others Binarization algorithms. I already installed Olena 2.0 under Ubuntu. Could you help me out with a little code SauvolaMs example ? For example how could I apply a SauvolaMs on a single page .tiff format and/or on many pages in .tiff stacks ? best regards Albert Berman, MSc Ben-Gurion University of the Negev Phone: +972-8-6477320 (office) Phone: +972-8-6477311 (lab) Fax: +972-8-6477627 P.O.B. 653 Beer Sheva 84105 Israel
