Description: Nick s binarization derives thresholding formula the basic Niblack algorithm, the parent of many local image thresholding methods. The major advantage of Nick s method over Niblack is that it considerably improves binarization for white and light page images by shifting down the binarization threshold.
The method description and comparison with other methods is available at http://dx.doi.org/10.1117/12.805827
