Diptychon is distinguished by a number of features which work both automatic as well as interactive. Among other things, textlines can be detected automatically, and afterwards, they can be adjusted interactively. A number of methods exist which enable the user to separate and combine regions. However, before starting to segment a word or a whole textline interactively, an automatic suggestion can be generated. Such a suggestion can also be made for a transcription. The quality depends much on the regularity of the writing and the amount of text known to the system. The eventual transcription can be searched through on the original document image.
