Historical documents contain generally different kind of degradations. Due to this degradations the application of methods of noise removal during a preprocessing stage seems to be necessary. Since the noise which, exists in the original document can not be eliminated using a simple noise removal algorithm and it influences the preprocessing result e.g. the binarization, a function of noise detection seems to be necessary. We present in this paper a method for the selection of the input parameters of binarization methods according to the noise type detected in the image. The tests are achieved on benchmarking datasets used at DIBCO 2009 and H-DIBCO 2010. The results returned by the binarization methods using the noise features are promising.
