Until the advent of the computer driven embossers,Braille was produced
manually or by embossing from a metal printing plate.As a result of
natural wear and tear,storage and transport, new copies must be obtained
at intervals , since the original plates no longer exist, reprinting the
material relies on manual copying. This is time consuming, labour
intensive and drain on limited resources, which results in material being
withdrawn from service. The aim of this paper is to describe a automatic
Braille translation system to store and recognize the Braille pages.
The
algorithms developed toke advantage of the regular spacing between Braille
dots within a cell, the regular spacing between cells and extracts any
required data from the image. The method has been designed and developed
to form a basis for translating single and double sided Braille.
Using thermoform solid dot Braille as the
specimen, the system has been proved to be more than 99% ( single sided
Braille page) and 93% ( double sided Braille page ) accurate on- the
translation of the Braille pages.
