ABSTRACT
There is a significant need for a system to recognise Braille documents in or-
der to preserve them and make them available to more visually impaired
people. Past approaches used expensive purpose-built and complicated
hardware arrangements and attempted to recognise only single-sided docu-
ments. This paper describes an approach to a prototype system that uses a
commercially available flat-bed scanner to acquire a grey-scale image of a
Braille document from which the characters are recognised and encoded for
reproduction or further processing. The system is flexible in that it is com-
pact, easy to set up and use and in that it also handles inter-point (double
sided) Braille documents. In addition, this solution is cost-effective since the
hardware can also be shared with other applications.
