Indian Currency Note Denomination Recognition in Color Images

It has been estimated that every five seconds, a person in the world goes blind. These visually impaired people have a reduced perception of the world around them and thus face a lot of difficulty in carrying out their day to day tasks. Even their problems go unnoticed from the sight of the normal people. The Indian currency notes have a size difference of just ten mm between two consecutive denominations and make it highly unlikely for a blind person to determine it correctly. Also, the new one rupee coin has the same shape and size as was of the old fifty paisa coin while both are in circulation and hence have become undistinguishable now. These problems make visually impaired people unable to do everyday transactions easily. As a part of currency recognition system for visually impaired, we have already developed an efficient currency note localization algorithm that localizes currency notes in color images. This paper uses the localized regions of the image and feeds it into the recognition module for determination of the denomination of currency note. We here present the developed technique to recognize the denomination of the Indian currency note from the color image and the results obtained, thereafter.
