Australian currency note identifier for the vision impaired: Part II software description

For pt.I see ibid., p.135-40 (2001). The article describes the software component of a prototype currency identifier. Identification is performed by imaging and recognising the contents of the clear window found near the lower corner of each note (I. Siewart, 1998), which is unique for each denomination. This development is of significance in Australia to people who suffer a large degree of vision impairment, and possibly also to the vision impaired population of the European Union, which may also plan to adopt polymer note technology.
