Old Czech Handwriting (with spaces)

Free Public AI Model for Handwritten Text Recognition with Transkribus

Old Czech Handwriting (with spaces)

This model is based on ground truth from three Old Czech manuscripts:
1) Padeřov Bible (Vienna, Austrian National Library, shelfmark Cod. 1175, 1432–1435)
2) Cistercian Bible (New York, The Morgan Library & Museum, shelfmark MS M.752, 1456)
3) New Testament of Martin Lupáč (Vienna, Austrian National Library, shelfmark Cod. 1175, 1440).

It can be used on Old Czech manuscripts written in bastard, primarily from the 14th and 15th centuries.

The transcription rules were based on semi-diplomatic transcription rules set by Pero OCR and “Směrnice pro vydávání starších českých textů” by Jiří Daňhelka.

Abbreviations were tagged and expanded. This model was trained on transcription, where spaces were created between words based on Jiří Daňhelka’s semi-diplomatic transcription rules (see above), regardless of the form in the manuscripts, and produced within the HTR Winter School 2023.
