Old Czech Handwriting (without spaces)

Free Public AI Model for Handwritten Text Recognition with Transkribus

Old Czech Handwriting (without spaces)

This model is based on ground truth from two 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),
bibles of the third redaction of the Old Czech Bible translation.

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. https://vokabular.ujc.cas.cz/moduly/edicnipoznamka.aspx?id=DanhelkaSmernice

Abbreviations were tagged and expanded. This model was trained on transcription, where the gaps between words were preserved based on the form in the manuscripts. Produced within the HTR Winter School 2022.
