Abstract :
For pt.I see ibid., p.129-34 (2001).The article describes the software portion of the research work that developed a prototype portable device for optically scanning embossed Braille and conversion of the scanned text to binary Braille representation. An application to convert the literary Braille code to expanded text has also been implemented. The system developed utilises a hand held scanner that captures the embossed Braille image in real time via a linear 128-pixel CCD array. A Texas Instruments Digital Signal Processor performs recognition processing.
