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
