Abstract : Present manuscript proposes a technique for estimating the angle of rotation for a Braille document image which in turn will be used for aiding its automatic character recognition.
The technique is based on maximizing number of null projection of the derived image vector.
Results show that any amount of rotation transformed distortion can be nullified and thus leading to proper reading of imprinted Braille character pattern.
The proposed methods have been successfully tested on manually written as well as computer generated Braille with rotation distortion.
