thank you for your answer i will take a look at your example and the leptonica library yesterday i looked for binarization algorithms. of course otsu is in this example no option. an adaptive algorithm is needed. i tried several like sauvola or niblack. at the moment best seems for me NICK described in this document http://www.math-info.univ-paris5.fr/~vincent/articles/DRR_nick_binarization_09.pdf
