Reconstruction of Broken Writing Strokes in Greek Papyri.

In the recent years, there has been an increased trend to digitize the historical manuscripts. This, in addition to preservation of these valuable collections, also allows public access to the digitized versions thus providing opportunities for researchers in pattern classification to develop computerized techniques for various applications. A common pre-processing step in such applications is the restoration of missing or broken strokes and makes the subject of our current study. More specifically, we work on isolated Greek characters extracted from handwriting on papyrus and employ a denoising auto-encoder to reconstruct the missing parts of characters. Performance evaluation using multiple evaluation metrics reports promising results.
