The implemented Sauvola method uses integral images for fast computation of the threshold function.

The Sauvola method is described in:

J. Sauvola and M. Pietikainen, Adaptive document image binarization, Pattern Recognition 33, 2000. - http://www.mediateam.oulu.fi/publications/pdf/24.pdf

The modification which uses integral images providing a 20-fold speedup (according to the paper) is described in this paper:

F. Shafait, D. Keysers, and T. M. Breuel, Efficient implementation of local adaptive thresholding techniques using integral images, Document Recognition and Retrieval XV, 2008 - http://www.dfki.uni-kl.de/~shafait/papers/Shafait-efficient-binarization-SPIE08.pdf

A paper evaluating binarization methods:
