D EFINING THE DOCUMENT CHARACTERISTICS
Next to the document language, other document characteristics such
as the Font type and Character pitch play an important role in the
recognition process.
Font type
Readiris distinguishes between "regular" and dot matrix printed
documents. Dot matrix symbols (of the type 9 pin) are made up of
isolated, separate dots.
Special segmentation and recognition techniques are required to
recognize dot matrix documents and need to be activated.
