Review Paper on Feature Vector Based Distance Analysis Approach for Braille Character Identification

The Braille is the representation based language used by blind people to perform conversation. Each Braille character itself represents some symbol or word or character specific to the language such as English. A Braille character is generated using group of dots. To identify the Braille characters in an automated way, there is the requirement of some recognition system. In this review paper, an automated neural network based approach is defined to perform the recognition. The character recognition is the application of image processing used to identify the character. This application is area needs a series of image processing operations, which help us in our research work.
