 ## Model description
 
 This model is part of on-going research on pure semantic segmentation models as a formulation of document image binarization (DIBCO).
+This is in contrast to the late trend of adapting classic binarization algorithms with neural networks, 
+such as [DeepOtsu](https://arxiv.org/abs/1901.06081) or the aforementioned SauvolaNet work, 
+as extensions of the classical Otsu's method and Sauvola thresholding, respectively.
