It is often difficult for the visually impaired people to identify the denomination of the currency note. To assist them easily determine denomination of INR currency notes, a team from IIT Ropar, Punjab has developed an Android App “Roshni”, using image processing and analytics.
"The user has to bring the currency note in front of phone camera and the App would provide audio notification intimating the currency note’ denomination to the user. The Roshni is the first Android App that works successfully with new INR currency notes also and it works well in broad range of light conditions and holding angles," the IIT said in a statement on Wednesday.
The team prepared a rich dataset of more than 13000 images of INR currency notes under varied real-world conditions. The team consists of Dr. Puneet Goyal, PhD Scholars - Mandhatya Singh and Joohi Chauhan, and a student R. Ram.
The IPSA (Image processing, Security & Analytics) Lab members visited the Chandigarh blind school recently and performed the App testing there. The App received very favorable feedback from the students and faculty members of this School.
“Roshni is turning out to be very beneficial for the visually impaired in easily recognizing INR currency and performing money transactions confidently and smoothly,” said Dr. Goyal, Asst. Prof, IIT Ropar.
