An Insight into Optical Braille Character Recognition since its Conceptualisation
C.N. Ravi Kumar · International Journal of Computer Applications · 2011
Language is the finest gift of god, for communication. Optical character recognition (OCR) is one of the active fields for research and development. Several researchers have presented different approaches to recognize various language characters all over the world. Recognizing printed and hand written characters are two different areas of character recognition. Louis Braille invented Braille language, which is used as the only way for reading and writing communication by blind people all over the world. Although English Braille is very popular, other languages also have their own Braille notations. In this paper we have made an effort to identify the different works carried out by researchers to optically recognize the Braille characters and to convert them into their equivalent normal language notation.
