emoCode.m shows how to extract hierarchical multiscale LBP features. GetMultiscaleLBP.m gets hierarchical multiscale LBP histogram for a given image distMATChiSquare.m computes the dissimilarity between training samples and a test sample

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. - ht
