// Purpose: An efficient implementation of the Sauvola's document binarization 
//          algorithm based on integral images as described in
//          F. Shafait, D. Keysers, T.M. Breuel. "Efficient Implementation of 
//          Local Adaptive Thresholding Techniques Using Integral Images".
//          Document Recognition and Retrieval XV, San Jose.
