A semantic segmentation model for pixel-wise document image binarization.

• fine-tune Segformer on 1024 $\times$ 1024 images;
• set reduce_labels=True in Segformer processor to ignore the background;
• compare valid DIBCO metrics with SauvolaNet's paper.

Segformer is an efficient semantic segmentation model introduced by Xie et al. in 2021.

In this repository, we will provide a fine-tuning of Segformer for pixel-wise document image binarization.

The dataset is an ensemble of 14 datasets replicating the setting used in SauvolaNet by Li et al. in 2021.
