IIT Ropar launchs an app ‘Roshni’ to help blind identify notes

IIT Ropar has launched an android app ‘Roshni’ to help the blind in recognizing the denomination of the currency notes, using image processing and analytics. At present, notes of Rs 10, 20, 50, 100, 200, 500 and 2,000 are in circulation, which the blind people find it difficult to recognize due to their size and the tactile marks. The app can recognize both old and new notes and gives audio information as to which note you are holding in your hands. The user has to bring the currency note in front of phone camera and the app would provide audio notification intimating the currency notes denomination to the user. The app uses the patterns and features embedded on the notes to differentiate and determine the currency denomination. The app is developed by assistant professor Dr Puneet Goyal and his students — Mandhatya Singh, Joohi Chauhan, and R Ram.
