Braille Character Recognition Using Generalized Feature Vector Approach
   
 
A technique has been developed for vision based braille printout quality assessment system. A generalized feature vector approach is used to extract the braille dots from the digital braille print, which is further utilized to measure the dot spacings for examining the printing quality.

 

This helps in providing the necessary feedback to the design team so that they can improve the printer prototypes accordingly. A simple but elegant approach to convert the braille code to running text using single sided and interpoint Braille print is also used. It can also be utilized in regenerating braille print from existing ones.
